Description
Technical field
The present invention relates to sewage treatment area, specifically a kind of sewage-treating agent and apply its method of disposing of sewage.
Background technology
Environment protection directly affects the Sustainable development of Chinese national economy.In the Economic development of China's the past few decades, owing to ignoring developing environment protection, result in the situation that present stage environmental pollution is very serious.Though took a large amount of measure of control in recent years, environment became bad trend further and was still continuing.China is one of the most serious country of environmental pollution in the world, no matter is city, or rural area, and the air of China, river, lake, ocean and soil etc. are all subject to pollution in various degree.Five cities such as Kweiyang, Chongqing, Beijing, Lanzhou are positioned at the row in the most serious city of the large atmospheric pollution in the world ten, in more than 600 city, the whole nation, air quality meet national standard reference less than 10.The degree of nationwide acid rain harm and region also expanding day.
In the annual sewage discharge in the whole nation, only the sanitary sewage of 10% and the industrial sewage of 70% are processed, and wherein about have the water outlet of half Industrial Waste Water Treatments facility not reach discharging standards, all the other untreated sewages then directly enter in rivers and lakes, cause the water surrounding of China to be subject to severe contamination and destruction; The quantity discharged of town domestic sewage is just along with city-building and development and in the trend increased progressively.According to statistics, in 110 key sections of the whole nation seven large water systems and inland river, what belong to 4 classes and 5 class water bodys accounts for 39%; Urban ground water pollutions is generally serious, and in the trend worsened further, 136 flow through in the river in city, belong to 4 classes, 5 classes and more than 5 class standards up to 76.8%; The urban groundwater of about 50% is subject to pollution in various degree; Larger freshwater lake such as the Eutrophic Extents such as Dian Chi, Taihu Lake and Chaohu in the whole nation aggravate year by year; The drinking water source in some areas is subject to severe contamination, causes serious harm to people ' s health.Municipal wastes and industrial solid castoff grow with each passing day, and trade waste adds up accumulating amount more than 6,600,000,000 tons, take up an area more than 50,000 hectares, and more than 200 city is absorbed among rubbish encirclement.
With regard to sewage disposal investment cost and working cost, calculate by ton water cost 1500-2000 unit and working cost 0.8-1.4 yuan/ton, the municipal sewage plant that China not yet invests to build needs one-time investment 1,000 hundred million yuan, add municipal pipe network construction, invest more than 2,000 hundred million yuan, annual running cost 25000000000 yuan again.And the fund of China's construction of municipal effluent plant, 90% comes from various loan, annual 20000000000 yuan for Sewage Plant construction, each project is on average repaid 10 years phases, and after several years, principal and interest will more than 30,000,000,000 yuan, and running cost and principal and interest account for 1% of China GDP; And current municipal sewage treatment, only have social benefit, there is no economic benefit, therefore, investment huge like this and working cost, to the China of economics of underdevelopment, a white elephant beyond doubt.
And determine that the principal element of municipal sewage plant's investment and running cost is the selection of sewage treatment process and technology, that current China urban sewage treatment process generally adopts is traditional activated sludge process, oxidation ditch, SBR etc., these ripe and effective treatment process, are widely used in various places.But for a long period, hamper the construction of municipal sewage plant of China because energy consumption is large, working cost is high, some sewage works built up are also because of the reason that energy consumption is high, are in stopping production and half end-of-life state for a long time simultaneously.Within one quite long from now on period, energy consumption problem will become the bottleneck of municipal sewage treatment.The energy consumption problem of Sewage Plant can be solved, rationally carry out energy distribution, become the key factor determining sewage work's on-road efficiency quality, also be the deciding factor of following new sewage work's feasibility analysis, exploitation is applicable to efficient, the low consumption of China's national situation and can meets emission request, and capital construction and the low New Technology about Wastewater Treatment of working cost and novel process, will be the only way of following Designing Sewage Treatment Plant and operation, be of great practical significance.
