Description

Integrated stabilization pond equipment for treating dispersive sewage
Technical Field
The utility model relates to a sewage treatment device, in particular to an integrated stabilization pond device for treating decentralized sewage.
Background
Along with the continuous improvement of the living standard of residents in China, the discharge amount of domestic sewage is increased day by day. The treatment of urban domestic sewage adopts a centralized treatment mode, namely, the treatment system consists of a sewage collection system, a centralized treatment unit and a treatment unit: the sewage collection system needs to be provided with corresponding collection pipelines, underdrains and necessary pressure lifting pump rooms to collect sewage into a centralized treatment unit in a sewage plant; the cost generated in the collection and transportation process usually accounts for more than half of the sewage treatment cost. For dispersed domestic sewage in rural towns, enterprises and public institutions, scenic spots, mines and sewage pipes which cannot reach areas, the centralized treatment mode is difficult to adapt due to the restriction of geographical conditions and economic factors, and a lot of point source sewage is directly discharged. At present, the traditional septic tank mode which is used in China all the time can only play a role in pretreatment, and is difficult to reach increasingly strict national standards. Therefore, the design and development of the integrated stabilization pond equipment for treating the dispersive sewage are necessary and efficient for making up the part which is difficult to realize large-scale treatment of sewage treatment, and the selection of the dephosphorization process also becomes a key technology.
In recent years, the discharge of a large amount of sewage containing nutrient elements such as phosphorus into a water body is a main factor causing water body eutrophication. With the stricter requirements on the phosphorus discharge standard at home and abroad, the sewage phosphorus removal technology becomes a research hotspot in the field of water treatment. The sewage dephosphorization technology can be generally divided into a biological method and a physical and chemical method. The biological method mainly depends on assimilation of activated sludge and microorganisms in a biological membrane to absorb phosphorus and then discharges residual activated sludge to remove the phosphorus, but the removal effect of the process is unstable, and particularly, sewage with high-concentration phosphorus is difficult to meet the standard for discharge; although the chemical precipitation method is stable and efficient in operation, secondary pollution is often caused, and even the addition of chemical agents can cause corrosion of equipment and the like. Compared with a biological method, the electrolytic dephosphorization technology has the advantages of high removal rate, strong selectivity and the like, and simultaneously, compared with a chemical precipitation method, the electrolytic method generates less sludge.
The dispersed sewage, especially the domestic sewage in remote areas and rural towns, has large fluctuation of water quality and water quantity in different water using periods. Therefore, the research and development of the dispersed sewage treatment process which has strong impact load resistance, low investment, low energy consumption, unattended operation, stable and efficient phosphorus removal capability is a necessary requirement for realizing effective control of dispersed sewage and is also a key point for restraining the eutrophication trend of domestic water bodies.
