Problems solved by technology

The physical treatment method is to put a large amount of flocculant (generally 500mg / l) and coagulant (generally 4mg / l) magnetic seeds into the sewage to flocculate the pollutants around the magnetic seeds, and absorb these with magnetic attraction The floc pollutants of the magnetic species can be used to remove the pollutants. Although this method can remove the sol-like colloidal pollutants and make the water clear, since the water also contains a large amount of nutrient-rich substances dissolved in the water, These nutrient-rich substances will lead to a large number of algae in the water, and are the source of the foul smell of the water. Moreover, the separated flocs have a large volume and become a kind of solid waste that is not easy to handle due to their large water content. A large amount of flocculants and coagulants dissolved in water will cause secondary pollution

Embodiment Construction

[0008] Now in conjunction with embodiment the present invention is described in further detail:

[0009] This embodiment sequentially includes a filtration process for filtering larger solids, a microbial sewage treatment process, and a physical treatment process. The microbial sewage treatment process includes an aerobic microbial treatment process and an anaerobic microbial treatment process. The physical treatment process is first. The water from the microbial sewage treatment process is put into powdery magnetic seeds. The particle size of the magnetic seeds is 0.5-100 μm. The magnetic seeds are evenly mixed into the water by physical stirring. The magnetic seeds evenly mixed into the water capture the fine microbial sludge in the water , and then the magnetic seeds in the water and the microbial sludge captured by them are sucked out by means of magnetic suction, so as to thoroughly treat the sewage. The magnetic seeds containing microbial sludge can be put into use again ...

Abstract

The invention provides a thorough sewage treatment method, which is characterized by sequentially including a microbe sewage treatment process and a physical treatment process, wherein the physical treatment process includes feeding powder magnetic seeds into water from the microbe sewage treatment process, sucking the magnetic seeds in the water together with the captured microbe sludge by the seeds via the manner of magnetic attraction, thereby the sewage is thoroughly treated. Compared with the prior art, the sewage treatment method has the advantages that pollutants in the sewage are thoroughly removed, no secondary pollution produces, and the water becomes clear.

Description

Technical field: [0001] The invention relates to a sewage treatment method. Background technique: [0002] The existing sewage treatment methods are either biological sewage treatment methods or physical treatment methods. The biological sewage treatment method is to remove the nutrient-rich substances of ammonia nitrogen contained in the sewage through aerobic and anaerobic biological treatment. This method can treat the inferior fifth-class water into first- and second-class water. Even so, the water still contains a large amount of The fine microbial sludge suspended in the water will affect the appearance quality of the water. Because it is a fine microbial sludge, it is not easy to settle down. The physical treatment method is to put a large amount of flocculant (generally 500mg / l) and coagulant (generally 4mg / l) magnetic seeds into the sewage to flocculate the pollutants around the magnetic seeds, and absorb these with magnetic force The floc pollutants of the ma...
