City sewage synthesizes , administer and circulate to use

--- - protect water resource administer and circulate for eliminating sewage and the river pollution of Shenzhen city use feel pulse

An Gang ( cool brain An)

Zong watch domestic and international city sewage administer scheme, they have common characteristic , that is " is having no alternative , under, extremely helpless condition, carry out sewage disposal, ", have produced from this administer sewage cost is , effect difference high , water resource basic not repeated usage. Invent personally, " Running water is not stale control theory with time " have synthesized physics, chemistry and the method of biology, adopt " in order to avoid mainly with, handle for supplement " Principle carry out sewage to administer. Initial stage, when sewage produce , handle it , strangle sewage in cradle , instead of the method of administering of current international universal adopting. This invention method have handling sewage cost is low , the water resource rate of repeated usage is 3 to 5 high( may reach , the quantity of water supply of one million tons of current / day is equal to extend to 300-five millions the quantity of water supply of ton / day).

Invent personally since adopting , " Running water is not stale control theory with time " carry out sewage factory construction and sewage recovery synthesize use, sewage factory run cost in average in ０. 3 Yuan ／ square level, is lower than Shenzhen city the average charge of sewage disposal of now ０ ． 6 Yuan ／ square level. Sewage factory handling qualified rear water, take the responsibility for recovery by government designated department( press 0. The / of 9 Yuan ton calculation) sell according to non drinking water( press the / of 1 Yuan ton calculation). So sewage factory annual handling the profit of sewage have the minimum / of 219 Yuan ton. Build its sewage factory ton water cost with current technology, normally in １ ５ ０ ０ to ２ ０ ０ ０ Yuan between, we sum according to the 2000 Yuan of upper limit, need 9. For 13 years, side can withdraw all investments. If the advanced theory of application me carries out the construction of sewage factory, its ton water cost need to be below only Qian first, most 4 years half may withdraw all investments.

It is expected that it is ten billions Yuan that Shenzhen administers sewage project total investment, in which, social investment takes eight billions Yuan at least, government most investment two billions Yuan. In 20 one-hundred millionses of government investment, reform 10 one-hundred millionses used in pipeline and Qing Wu of river course, 10 other one-hundred millions transfer cost ( do not sum income tax) for my service and intellectual property. Since adopting I administer scheme, build sewage factory investment profit is " BOT " or " TOT " high very much, so sewage factory construction carry out way prospect will very wide. Sewage factory construction government need not not only make investment , may get profit from the tranfer right of administration of special permission more, ( assume according to the investment idea of 10% of return rate , the handling of government water recovery price is 0. The / of 6 Yuan ton). May pay river course transform and my service cost with part or all tranfer profits of special permission of right of administration, according to the four millions tons of daily calculation of water consumption, government has 4 every year at most. The income of 3,800,000,000 Yuan. Needs 5 years time government can accomplish to administer sewage and recovery river original look not only do not make investment , still have financial profit My guarantee is being administered sewage project all( in the total 5 years of project time limit) completions after, in Shenzhen whole boundary own from Shenzhen river, cloth lucky river and dragon hillock river etc. the original first beginning of river arrive enter big sea , will realize river whole boundary free from contamination resume river original look , let wear the river of city become city floating scenery line.

Administer Implementing method is: By mayor or reponsible associate mayor, take command personally , is project consulting adviser personally, I uses " Running water is not stale control theory with time " guide project program and construction. The effect of me for total project is taken the responsibility for , project time limit, quality and the investment for specific project are not taken the responsibility for personally, is been. As inviting any global city of me, take service consuming one-hundred millions dollars, from. Since this writing is published day from, per postpone one month invite , its charge increase 6% ( calculate according to compound interest). Note: ( receive knowledge service cost personally is without individual income tax). As before June 30,2003, inviting the first Chinese continent city of me, I takes according to Rmb ( 1 Americas round = 1 Rmbs), other city according to beautiful round settlement. When government determines to invite me to ask consulting adviser first my payment 30% when my guidance completion is administered when project is planed , pays 40% again , pays remaining 30% finally in project completion.

I administer pollutive method is brand-new invention theoretical, though theoretical can not patent application, but apply this theory produce administer pollutive equipment and technology just may patent application. It will inevitably become the production of the new equipment of environmental protection to research and develop center that everybody first uses who, the patent tranfer and equipment sale profit that brings from this absolutely do not be Bai one-hundred millions America round is beautiful round of hundred billions.

The pollutive condition of Shenzhen and the method of administering of current government introduce

Shenzhen is a nearly have no what industry, with the frontier little town mainly with natural economy , also have no industrial pollution, ecological environment keeps basically in original state. In special economic zone at the beginning of establishment dragon hillock and the mountain two river water of level ground may clean out , metre is washed vegetable, Shenzhen river can still swim. Along with the economic development of Shenzhen, city construction step accelerates , population grow constantly, soil erosion and river water change dark ammunition smelly etc. environment problem follow produce , the environmental protection of Shenzhen look increasing urgent. There are the size river strips more than 160 in Shenzhen city, divide to belong to gulf, eastern river and pearl river, 3 water departments. Since by the influence of topography and landforms, remiting water area to be larger than the river of 10 square kilometers only, Sub_clause of 13 is larger than 100 square kilometers have only Sub_clause of 5, difference is Shenzhen river and Mao Zhou He , watch Lan river, dragon hillock river and the country land of level ground. Cloth lucky river is the major tributary of Shenzhen river. From cloth lucky river head head begin , go through cloth lucky town, close after " second line ", compensate for people's bridge again along railway line, final coming Shenzhen river and the cloth lucky river of fisherman village deliver remit place, total length 16 kilometers. In the major fountainhead of cloth lucky river — — — the bank of water way river, head-on come except pile up rubbish mountain, is everywhere evidently simple shack. Hope that a little stream has overflowed, shack side layer upon layer rubbish, remit a share rare delicacy pungent turbid water, postpone Zhi land swim downward flow. According to introduction, these rejects are collected and raised the shack of pig, as if psoriasis the same, relevant aspect though put in order again and again still go reply. The smell of cloth lucky river is only from these shacks. Cause cloth lucky river to pollute to change smell, " main murder ", is still sewage. Wear the cloth lucky river that cloth lucky town passes , may become a beautiful scenery of this town originally, but become the blowdown of bank resident unfortunately, " sewer ". In cloth lucky town innumberable families day the sewage of the ten thousands tonses more than 10, do not nearly enter river course by handling for direct emission. Cloth lucky river water again lean rainwater supply mainly, so when not raining , this river nearly becomes " the ditch of stagnant water ", in river slow flow shed is sewage completely. These sewage direct currents enter special zone , cross downtown, give off to rush, in day, stink becomes bank resident " the pain of a heart ". Cloth lucky river has become Shenzhen " dragon must ditch ". Besides special zone town rubbish empty at will, , stack phenomenon very universal, some rubbish heaps put site even set up in the protection zone of source of water. Flow out the river by the city proper to become the rubbish heap of bank resident, put site, rubbish is eroded by rainwater , causes serious pollution for source of water. Besides in the second line of special zone periphery and river upper reaches section, harbor especially remote mountain, spread the pig farm of size, these pig farms become " the undercurrent of river pollution ", watch Lan river, dragon hillock river and the country land of level ground get aquaculture pollutive influence with Mao Zhou He biggest.

Need to raise fund in many ways to administer sewage, to strengthen river pollution, administer work, the Shenzhen city consideration of the Standing Committee of the NPC has passed through " the Shenzhen source of special economic zone of drinking water is protected regulation " ( revise ). It is that Shenzhen city administers a important measure of sewage to quickly build sewage treatment plant. Only dragon hillock district have built with in build sewage treatment plant have 7. Now, Shenzhen city tries operation management enterprise in the aspect of management and the construction of sewage treatment plant, melt raise the pattern of diversity with capital: If dragon field sewage treatment plant determines the Shenzhen bluish green cloud day company's and Anhui country of environmental protection with the form of open public bidding Zhen the operation maintenance of the company of environmental protection contract unit always; China for sewage treatment plant from the Shenzhen dragon hillock district precious praiseworthy new investment investment construction and operation of limited company; After horizontal hillock sewage treatment plant establishes , sells adopting , the way of right of administration is transfered to the enterprise operation of sewage disposal of specialization.

The major source condition of Shenzhen river and cloth lucky river pollution

A, industrial pollutive source Produce in various industrial productions, useless water emit into water body have caused industrial pollutive source. The different industrial effluent produced by industry in contain contaminant have great discrepancy fully, this is because of the raw material of various industrial processings difference and process difference cause. The useless water produced by metallurgical technology has cooling water mainly , wash water with wash water etc.. The water of direct cooling in cooling water since in which containing suspension thing etc. and the oxide of oil and iron with product contact; Wash water, to have dust-clearing function and purify , gas and flue gas in which contain phenol, cyanogen, vulcanization cyanogen sour salt, vulcanization thing, sylvite, tar, suspension thing, ferric oxide, lime and fluorine with water to melt thing and sulphuric acid etc.; Wash water, in contain acid , reduce , oil, suspension thing and zinc , tin, nickel and chromium etc.. In above-mentioned useless water with contain cyanogen , contain phenol useless water harm biggest. Colored metallurgical industry is discharged useless water, contain mercury, arsenic, tin and chromium etc. element , is the source of the contaminant of heavy metal in water body. Besides, colored metallurgical remained plenty of slags are washed by rainwater, flow in the face of land and underground water to become water body, suspend contaminant. Light industry is processed raw material is farming byproduct , therefore industrial effluent contains machine quality mainly , still contains plenty of suspension material, vulcanization thing and heavy metal sometimes frequently, such as mercury, cadmium and arsenic etc.. The product of chemical industry is many , therefore chemical industrial effluent ample also very complex, contain frequently in useless water various is harmful , poisonous, even drama poison quality, such as cyanogen, phenol, arsenic and mercury etc.. Some material is hard it is enriched that degradation can but pass through food-chain in organism , cause harm , unite stupid etc. as DDT and much chlorine. Besides, in chemical useless water some have more strong acidity, some show than strong reduce sexual, PH value instability, these useless waters have harm for the ecological environment of human body, the building facility in water body and crops contain nitrogen in, some useless waters , Lin is water body eutrophication high very much, is easy cause. Some contaminant even if content very tiny, but circulate through the material of food-chain enrichment, can cause aquatic animal and person is poisoned. In a word industrial pollutive source to water system emission, big useless water has quantity, is big , surface broad, ample complex characteristic, is the pollutive source of key solution.

2 and city sewage
City resident assembles the sewage produced by region, is wash water with erode implements produce sewage, therefore, major from have no poisonous organic matter somewhat, such as carbohydrate, starch, cellulose, oil, protein and urea etc. composition. In which, contain nitrogen, , Lin , sulphur higher. Besides, return companion, have various detergents, this is another kind of pollutive source, they have certain harm for human body. In sewage the microorganism that still contains considerable quantity in which some pathogeny bodies as germs, virus and parasite etc., have greater harm for the health of person. According to the partial industrial information statisticses of developed country, the city life approximate each daily 150-420 of water consumption rises , especially big city rises for 440-820.
3, rural sewage and irrigation water
Rural sewage and irrigation water are the major source of water body pollution. Since farmland is used chemical farm chemical and chemical fertilizer and irrigation after or go through rainwater will farm chemical and the tape of chemical fertilizer cause the eutrophication or pollution of farm chemical into water body. In sewage irrigation district, river, reservoir and underground water can arise pollution , at the same time also arise soil contamination and food contamination.

Shenzhen river possess some of tributaries in special zone, in which, the pollutive influence of cloth lucky river for Shenzhen river is biggest , its pollutive 60% that takes Shenzhen river pollutive amount. Deep Hong Kong's two places are united from 1995 administer Shenzhen river. Now, as soon as the project of 2 issue has been completed in 1997 and 2000, the project of 3 issue has started. Is recent , Shenzhen river administer the project of 4 issue( invest in 9. Five-hundreds millions Yuan) may in advance trip research have been completed , the project of 4 issue will arrive in Shenzhen gulf big Peng gulf dig the artificial river course of a 10 kilometers of length open, use big Peng gulf and the tide difference of Shenzhen gulf will Shenzhen river water is unidirectional floating from the floating change of round trip of now, unceasing tape go to sewage, thorough change water quality. After project is completed Shenzhen river prevent flood ability will meet raising from one of 50 years meet , 500 tons of level pearl river to one of 200 years water department fleet may run directly from Shenzhen gulf big Peng gulf, the through port of salt pan and ocean transportation is linked receive. At the same time on river, travel has developed , bank economic trade and real estate have been developed. About this tentative idea, actually, publish in 1995, " Shenzhen special economic zone start business history " have had record, in a book, source in the previous Shenzhen secretary of municipal Party committee strictly promising suggestion! 4 issue estimates to finish working in 2005 years, according to the words of government, this project joins for promoting deep port, promoting the prosperity of Hong Kong stabilize to have longterm meaning , is the Shenzhen city improvement city environment of next step , change the one of crucial project of city business look. Shenzhen river will become to have water conservancy, economy, culture, landscape and the beautiful well-known river of social comprehensive benifit.

Author viewpoint: In this one magnificent from big Peng gulf abstraction is completed into Shenzhen river project after, have diluted the pollutive condition of Shenzhen river though because of the seawater of plenty of uses, however have arisen a larger ecological disaster just our, beautiful red woods will perish since have no fresh water. Excuse me Shenzhen person, you have destroy " red woods " right?

Attach: The Shenzhen field red woods national introduction of good fortune of nature reserve

Location: 22° 32′ N114° 03′ EShenzhen river river mouth and Shenzhen city boundary. Area 304Hectare, include 228Hectare red woods. Elevation 0 ～ 3Metre. Describe wetly: Extend with Shenzhen river mouth to west 11.5Shrimp and the fishpond of kilometer pool, red woods region and Shenzhen river the adjacent tide of lower reaches of river mouth between sandy beach and mud beach. This wetly with the metre of Hong Kong Pu swamp is adjacent. A lot of fishponds are deep 1Metre is much , shrimp pool water level is easy to receive the tidewater fluctuation that has law , makes it fluctuate on spring tide line with the method engineering of tradition. Salinity in 17.6～ 21.8p· p· t Climate condition: Tropical monsoon climate and annual average rainfall 1,950Millimeter, year temperature 22.4℃( highest 36℃, minimum 1℃), average relative humidity 79% Major vegetation: On mud beach some seaweeds. Vanguard red woods have following advantage to grow, is mixed: In autumn eggplant and tung coloured tree with sea Lan female, have sea lacquer in river course rein with mouse. Mature red woods crowd clump with autumn eggplant and wood Lan with red tree Jue, sauce Jue grow for advantage. The other kind that exists includes sea mulberry and red sea Lan with fish cane. The vegetation in shrimp pool includes reed marshes, nutgrass flatsedge and rat-tail Su, embankment last scattered growth the moss grass and grass of standing grain( as: Knot thread grass, sparrow barnyard grass and rat-tail Su with float touch grass) with soda Peng, sand have smelly tree peony, sheep knee, rich bud chrysanthemum, dew son tree and thorn on the ground Kui with sweet potato mix crowd fall. On the inland edge of protection zone recently, have planted Taiwan longing.

Wetly birds: Have recorded birds, 95 kinds in which non sparrow shape eye bird 46 kinds, Lu kind of kind and quantity with a maximum of, 11 kinds, with white Lu , pool Lu grow for advantage, is ox the back secondly Lu, yellow mouth white Lu , in white Lu , night Lu wait , winter with sandpiper and with the duck of wild goose mainly with green wing duck kind. Still have , Lu Ci, white bone carry , red mouth Ou. Record the kind of more few quantity to include roll pelican, ( January 1986 15, January 1988 33), white stork( January 1988 2), dark face Pi Lu( January 1988 28) with dark mouth Ou, move , arise plenty of sandpipers especially in spring. Fish hawk with hoary head Yao is also this land live through the winter bird. Other animal: Sand quality tide beach has fairly rich sea raw inverebrate, have recorded 36 kinds, include 18 kinds of petal branchia, kind has the mud of pincers department Han , than that Han, angle hair Han, cloth veins Han; She of curtain clam department Sa uncle curtain clam and scale Biao take clam , Zhui brocade clam, green clam, writing clam and Japanese mirror clam; The transparent cherry clam of cherry clam department; Bamboo Cheng department Yi Cheng; The 4 angle clams of clam department; Sea Lang the sea of department Lang; The cat who does not wait for oyster department and the sea month of clam department claw oyster; Xian the river of department Xian wait; 9 kinds of belly enough kind has bank snail and pearl tape to draft crab, guard snail, litchi snail and spot jade snail , red tree draft crab guard snail, among draft brook snail , draft dark snail , purple swim snail and stone sulphur; 9 kinds of crust kind, have arc side to recruit tide crab and grand the back, big eye crab, drum shrimp, saw reason green crab and China are for shrimp , knife volume new for shrimp and spine end white shrimp etc.. Crawl , kind includes water snake and shading water snake , know about this kind of snake very less, recent just believe it exist in Hainan. Peculiar plant: Since being near big city centre, the field nature reserve of good fortune has very rich red woods crowd to fall. Therefore as scientific research and nature are protected , education has great potential.

Economic and social value: Red woods for the very important crust on a lot of economies, kind and fish have offered rich bait material and grow seedlings place, in the aspect of stabilizing coast line, have considerable value. Fish and shrimp pool have offered important income source for local people, mud beach support very important oyster aquaculture, nature reserve is protected for the nature of nearby city people education has offered good place.

The current sewage of Shenzhen municipal government is administered goal

According to municipal government, synthesize to administer overall program, the sewage of cloth lucky river is administered goal divides into 3 stages, ( 2001 to 2003 years) reduce substantially enter special zone pollute measure , guarantee realization special zone water quality have greater improvement; ( 2004 to 2005 years) ensure enter special zone cloth lucky river water quality reach a level emission standard, in the inland river of special zone section realize the water body landscape of river course; ( 2006 to 2010 years), perfect cloth lucky town city construction system, cloth lucky river all fronts reach the quality V of surface water kind of standard, realize the river function of ecological environment. Construct grass, Pu sewage treatment plant, in special zone the outside region of upper reaches take out take the partial rainwaters and sewage of dry season, put into the river of lower reaches again after handling in. Complete sewage treatment plant in June 2002, first issue project is solicited land take apart move with the first phase project of dredging waterway the base of 2003 years establish sewage treatment plant first issue project put in use. The recent scale of the cloth lucky river sewage disposal of upper reaches is the daily cubic metre of one hundred and fifty thousands surely. Near future project will still establish the valley sewage of upper reaches to collect systematic, complete sewage and the section of rainwater get typeset , the 589 complete cloth lucky river metre long river courses of upper reaches are administered , the river course above complete five-hundreds thousands side is settled , silt , administer the area 1 of soil erosion, ． 18 square kilometers. In entire near future project budget investment 1 ． 374,300,000,000 Yuan.

The staff of a city department of environmental protection says to reporter introduction that basis has been built , is building the actual condition of sewage factory , ton water cost normally in １ ５ ０ ０ to ２ ０ ０ ０ Yuan between, operation cost in ０ ． ８ Yuan Zhi １ ． ４ Yuan between, establish a day handle ５ the city sewage factory of ten thousands tons of sewage, oneness investment cost want near one-hundred millions Yuan, annual operation cost is １, ４ ６ ０ ten thousands Yuan to ２, ５ ５ ５ ten thousands Yuan, with such huge investment and operation cost, for economy is yet not developed our country can not stand heavy burden. Compel in the urgent need of the current control of water pollution and the pressure of capital serious shortage, the existing city sewage factory construction of our country adopts foreign loan generally. The condition that gets foreign government loan is often to introduce the supplemental equipment that loan country whole set of equipment is sewage treatment plant. At the same time, rely on import and foreign loan in large quantities to introduce instrument etc. and the mechanical equipment of city sewage factory , and is many repetitive transfer, cause the city machinery and instrument equipment market of our country of sewage disposal, occupy for a long period for foreign product, serious retardance the development of domestic equipment manufacturing industry, make national plenty of foreign exchanges run off , at the same time still carry heavy foreign debt. According to reporter, understanding is aimed at sewage disposal can't do it present situation, people have begun explore new way out, now form following common recongnition having more and more persons: Government should fade out step by step as investment main part what the construction of sewage treatment plant take it over is that social capital with " Ｂ Ｏ Ｔ " way is the investment main part of sewage factory, take the responsibility for enforcement by enterprise the investment of environmental protection of government, include investment project design, construction and project establish rear operation. For have established sewage factory wait for large scale public infrastructure, carry out " Ｔ Ｏ Ｔ " way running, come through the right of administration of tranfer sewage factory raise capital, will the facility of sewage disposal evaluate rear tranfer give social capital, assign side enjoy in certain period specialize in right, expire after free will right of administration turn over to government. For above second kind condition, Shenzhen has now enacted related policy, " Shenzhen city deepens to throw financing system reform guidance opinion " put forward clearly " will carry the financing way of 'ＴＯＴ' actively forward , pass through tranfer large scale infrastructure( as sewage factory) the right of administration of project raise capital. "

So, in Shenzhen, carry out this practice, whether are you feasible? Take this problem, reporter has visited the flat lake factory director of sewage treatment plant to open flood. He says , comes according to present situation to see, in Shenzhen and even carry out nation wide " Ｔ Ｏ Ｔ " is faced with two big difficulty: As soon as the charge of sewage disposal is low. The charge of sewage disposal of Shenzhen is only ０ ． ３ ４ Yuan ／ square, nation-wide high place also is however ０ ． ５ Yuan ／ side, according to socioeconomy development level the cost of sewage disposal will rise considerably is not reality ( from January 1,2003 from the consuming adjustment of sewage disposal is: Resident 0. The / side of 5 Yuan administration uses water 0. The / square, industrial water 0 of 6 Yuan. The / square, business water 0 of 6 Yuan. The / side of 7 Yuan ); 2 the existing handling of sewage treatment plant cost house is no less than high. The region average cost of East China is ０ ． ６ ５ Yuan ／ square, Guangdong region operation cost is ０ ． ４ to ０ ． ６ Yuan ／ side, is the Shenzhen hollow of the first domestic operation of public bidding Zi dragon field sewage factory also need ０ ． ４ Yuan ／ side. On this foundation, do " Ｔ Ｏ Ｔ ", government must carry out financial subsidy in large quantities , or " dig eastern wall to mend west wall, ", can not form the situation of a virtuous circle. Zhang Hong thinks that solve above-mentioned problem, have following method: One is the cost of sewage disposal should make proper raising, as Shenzhen, rise arrive ０ ． ６ Yuan ／ should be may accept. 2 is that existing sewage factory must set up market melt , viewpoint, carry on technical innovation and internal management system reform , reduce cost, so, then can offer for social capital, one reasonable enter space, guarantee state-owned asset value get reasonable embodiment. Carry out " Ｔ Ｏ Ｔ " to manage way , is that Shenzhen accelerates the construction of sewage treatment plant, raise the ability of sewage disposal, is helpful to explore. So, from the Shenzhen existing enterprise of sewage disposal, whether have implement the condition of this move? Reporter levels lake sewage treatment plant through interview to feel, this factory, have now had such condition. This factory in １ ９ ９ ９ year is in operation formally, original handling ability is ２ ． ４ all places ／ day, operation cost is ０ ． ４ ３ Yuan ／ side, endure carry out " in factory, market melts " reform with technical innovation transform the rear raising of treating capacity arrive ５ ． ５ all places ／ day, operation cost is ０ ． ２ １ Yuan ／ side. If according to the tranfer idea of right of administration of 20 years, social capital is invested in return rate is ６ %( ton water cost press ０ ． ４ ０ Yuan ／ pay ( capital ２ ０ year share completely). Through calculation, before reforming this factory value of right of administration of 20 years is － ２ ３ ８ ． ９ １ ten thousands Yuan; After reforming this factory value of right of administration of 20 years is ３ １ ５ ２ ． ２ ７ ten thousands Yuan. Not than do not know , one than scare one jump! See through comparing we, if in now, social capital is thought of , gets this factory right of administration of 20 years, must pay , ３ １ ５ ２ ten thousands Yuan enter cost definitely. Before this, government will pay on the contrary ２ ３ ８ ten thousands Yuan can just have person contract. Thus it can be seen, this factory now have completely to carry out " Ｔ Ｏ Ｔ " the condition of mechanism.

Zhang Hong has calculated such one to reporter Zhang: According to existing nation-wide average operation cost ０ ． ６ Yuan ／ square, sewage annual treating capacity １ ０ ０ one-hundred millions square calculation, as picture level lake factory will cost fall , country press ０ ． ６ Yuan ／ square valuation carry out " Ｔ Ｏ Ｔ " the tranfer right of administration of 20 years talk about , may obtain contract ３ ５ ０ one-hundred millions Yuan tranfer cost, this action have not only thrown heavy burden, may also get valuable capital is used in the city's infrastructure construction.

Have seen , on about Shenzhen municipal government now administer method, we may discover , if will reach me put forward Recovery river original look So no matter investing in amount and Shenzhen municipal government to use existing method, is to be impossible to reach. Is to reach landscape requirement , it administers the total investment of river is also as high as , Bai one-hundred millions Yuan, sewage administer will make investment larger( government do not become heavy burden for guaranteeing sewage factory, for will burden shift to customer, is so do not be all right ).
