Description
Technical field
The present invention relates to sewage and industrial organic waste water process field, be specially a kind of buried Sewage treatment systems.
Background technology
China is a country that drought and water shortage is serious, and the Freshwater resources total amount is 28000 billion cubic meters, accounts for 6% of water globe resource; Be only second to Brazil, Russia and Canadian; Occupy the 4th in the world, but have only 2300 cubic metres per capita, be merely world average level 1/4, the U.S. 1/5; Ranking 121 in the world, is one of 13 countries that water resources is the poorest per capita in the whole world.
According to monitoring; Present national most cities underground water receives point-like and planar pollution to a certain degree, and the trend that increases the weight of is year by year arranged, and the while is along with the progress of society; The raising of people's living standard; Economy and Increase of population more and more receive the mankind's attention to the pollution of the Nature, and therefore curbing environmental pollution becomes important topic at present.The sewage sludge that for example is on the rise has not only reduced the functions of use of water body; Further aggravated the contradiction of shortage of water resources; The strategy of sustainable development that China is being implemented has been brought and has been had a strong impact on, but also serious threat is to city resident's safe drinking water and the people's health.
City domestic sewage discharging at present also has been the primary pollution source of China's municipal water; It is the most important thing of urban water conservation at present and in the future and Urban Water Environment protection work that city domestic sewage is handled, and the construction of processing sewage facility also becomes the important content of urban infrastructure.Though China has built up more than 100 of sewage work; But also can not satisfy the needs of city industrial and agricultural production and people's lives far away; The processing rate that shows some cities itself is not high; The amount of WWT just is not enough, shows that also the big city has taken up to carry out the planning and the construction plan work of sewage work's construction.But in small and medium-sized cities, particularly also the planning construction of WWT is not included in the agenda of urban development in small and medium-sized cities, the northwestward, its one of the main reasons does not have special construction fund exactly; The geographic water that has pollutes and is on the rise; If wait for when fund input is arranged and build sewage work again, environment is aggravated, make troubles to people's lives; People's physical and mental health is brought harm; So impel us to raise fund in many ways, accelerate the improvement of water environment pollution, more efficiently way is to find the mode of simple economy to come Treating Municipal Sewage and organic industrial sewage.
From the above; Global environmental pollution and shortage of resources have caused the again thinking of people to development problem; The proposition of Sustainable development idea makes the technology of present stage environmental area that strategic turnover take place; The continuous development of sewage disposal technology and practical applications have changed into to maintaining the necessary component of social economy's Sustainable development, and flocculation sediment, sand filtration system are generally all adopted in traditional WWT, and design adds the iron(ic)chloride medicament in A2/0 system final deposition pool distributing well; Enhanced biological phosphorus removal, the concentration of phosphorus in the water outlet of reduction final deposition pool; The post precipitation water outlet is adopted air-water backwash filter through promoting pumping plant to sand filter, filters back water to clean water basin, and the pressurization back gets into the reuse water pipe network.And along with the develop rapidly of science and the continuous progress of society; Based on physics; The various sewage treatment process of chemistry and biology principle constantly occur; Wherein the application of biologic treating technique is the most extensive, has become the main flow technology of municipal effluent and organic industrial sewage handler, for example adopts biologic treating technique and the buried sewage disposal device that grows up.
Though the buried sewage disposal device of this type simple economy that occurs in the market uses more and more widely; But all there are some problems; For example device structure is complicated, and the living weight during processing is less, thereby the metabolic function of mikrobe influences the processing efficiency and the effect of entire equipment slowly; Active sludge coagulative precipitation performance is not strong, and dispersed and practicality is relatively poor or the like; Simultaneously in small and medium-sized cities with increasing the crowd is dense that the district sets up relatively difficulty of large-scale sewage work; Except lacking of capital; More and more nervous land resources makes that also the selection in sewage work factory site is extremely limited, and cost of investment is high, and economic benefit is low; So the dispersion treatment that can only adopt buried sewage treatment equipment that the sewage that produces and waste water are carried out the subregion branch, but there are the problems referred to above again in present employed buried sewage disposal device.
