Domestic sewage treatment device

Abstract

The invention relates to a domestic sewage treatment device which comprises eight relatively independent reaction units of an anaerobic tank, a facultative tank, a primary aerobic fluidization tank, asecondary aerobic fluidization tank, an aerobic illumination phycomycete symbiosis fluidization tank, a primary aerobic ecological tank, a secondary aerobic ecological tank and an ecological sedimentation tank, wherein the eight reaction units are in serial connection. Or some reaction unit except the ecological sedimentation tank can be repeatedly arranged according to need to be in serial connection to form a reactor more than eight levels. The sewage treatment device disclosed by the technical scheme of the invention has a biological-ecological synergistic technical effect in effectively treating and reusing domestic sewage on site.

Description

technical field [0001] The invention relates to a domestic sewage treatment device, which belongs to the field of environmental engineering. Background technique [0002] At present, most of the decentralized domestic sewage treatment in our country adopts a single biological treatment process or a single ecological treatment process. Both of these two methods have some shortcomings: although the biological treatment process occupies a small Disadvantages such as large output, difficulty in realizing nitrogen and phosphorus resources, and poor landscape effects; although the ecological treatment process has low operating costs and good landscape effects, it often has shortcomings such as large area occupation and unstable water output. Insufficient sewage treatment process, the development of bio-ecological synergistic treatment process, through the coupling of the two processes to make up for their respective shortcomings, has become the mainstream direction of the current ...

[0002] At present, most of the decentralized domestic sewage treatment in our country adopts a single biological treatment process or a single ecological treatment process. Both of these two methods have some shortcomings: although the biological treatment process occupies a small Disadvantages such as large output, difficulty in realizing nitrogen and phosphorus resources, and poor landscape effects; although the ecological treatment process has low operating costs and good landscape effects, it often has shortcomings such as large area occupation and unstable water output. Insufficient sewage treatment process, the development of bio-ecological synergistic treatment process, through the coupling of the two processes to make up for their respective shortcomings, has become the mainstream direction of the current decentralized sewage treatment process development, but there are not many successful technologies that can better combine the characteristics of the two processes See, we need to develop a more reasonable processing method
