Anaerobic-aerobic-microalgae coupling treatment device and feces and/or domestic sewage treatment method

Abstract

The invention relates to the technical field of sewage treatment, in particular to an anaerobic-aerobic-microalgae coupling treatment device and a feces and / or domestic sewage treatment method. The anaerobic-aerobic-microalgae coupling treatment device comprises: an anaerobic tank (5); an aerobic aeration tank (8) communicated with a water outlet of the anaerobic tank (5); an aerobic-microalgae mixing tank (14) communicated with a water outlet of the aerobic aeration tank (8); and a microalgae pool (18) communicated with a water outlet of the aerobic-microalgae mixing pool (14). By adopting the device provided by the invention, feces and domestic sewage can be treated at the same time, and the quality of treated water meets the first-grade B standard of domestic sewage discharge; besides,a microalgae product is obtained while feces and domestic sewage are treated, can be used for producing high-end organic agricultural products and has better economic benefits.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an anaerobic-aerobic-microalgae coupled treatment device and a method for treating manure and / or domestic sewage. Background technique [0002] At present, aquaculture manure is usually treated by anaerobic method, and domestic sewage is usually treated by activated sludge aerobic method. It is a mixed sewage of various feces, kitchen production, household cleaning, domestic garbage dumping and percolation, etc. The types are complex, and the composition and concentration of pollutants fluctuate greatly, so it is difficult to use the current treatment process for a single source of sewage. Contents of the invention [0003] The purpose of the present invention is to provide an anaerobic-aerobic-microalgae coupling treatment device, which can treat manure and domestic sewage by using the device provided by the present invention, and is suitable for various types of wast...

AI Technical Summary

Problems solved by technology

[0002] At present, aquaculture manure is usually treated by anaerobic method, and domestic sewage is usually treated by activated sludge aerobic method, but the above methods are usually only for a single type of sewage, and there are many sources of sewage in rural sewage, usually It is sewage mixed with various kinds of manure, kitchen, household cleaning, domestic garbage dumping and percolation, etc. The types are complex, and the composition and concentration of pollutants fluctuate greatly. It is difficult to use the current treatment process for a single source of sewage to solve the problem.
