Abstract

The invention discloses a sewage flocculant. The sewage flocculant comprises polyacrylamide, citric acid, compound microorganisms, polyferric trichloride and bentonite. The flocculant has good flocculation and can reduce the sewage turbidity and improve the sewage treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage flocculant. Background technique [0002] Most industrial wastewater has complex components and high chroma, and contains many heavy metals and organic substances that are harmful to microorganisms. The requirements of flocculants put forward higher requirements. Contents of the invention [0003] The object of the present invention is to provide a kind of sewage flocculant aiming at the defects mentioned above. The flocculant can play a good role in flocculation, reduce the turbidity of sewage, and improve the efficiency of sewage treatment. [0004] The technical scheme of a sewage flocculant of the present invention comprises polyacrylamide, citric acid, composite microorganisms, polymeric ferric chloride and bentonite. [0005] Specifically, it comprises the following components by weight ratio: 5-6 parts of polyacrylamide, 1-3 parts of citric acid, 3-5...
