Problems solved by technology

[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

Embodiment Construction

[0041] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings and examples.

[0042] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

[0043] See attached figure 1 - attached image 3 .

[0044] This process is used to treat sewage in a residential area in Wenzhou City. The total population of the community is 1,000 people, and the daily sewage is 100 m3. The average concentration of collected domestic sewage is 350 mg / L COD, 40 mg / L ammonia nitrogen, and 5 mg total phosphorus. / L.

[0045] After the domestic sewage in the community is collected uniformly, it enters the 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 ...
