Problems solved by technology

[0002] The treatment of industrial sewage plays a very important role in protecting the environment. At present, there are still many problems in sewage treatment plants, such as unstable water quality, high operating costs, and the purified water needs to be disinfected by liquid chlorine, which leads to water pollution A large number of microorganisms in the medium die, resulting in the loss of self-purification ability of the water body, and the high chemical composition of the sewage treatment agent causes secondary pollution, etc.
However, simple microbial decomposition is slower than chemical treatment agents, and it is not easy to get quick results. How to combine microbial treatment with chemical treatment is a problem to be solved in the present invention.

Abstract

The invention discloses an industrial sewage treatment agent, comprising polyacrylamide, silicon dioxide, peroxysulphate, sodium carbonate and compound microorganisms, wherein the compound microorganisms comprise bacillus licheniformis, pseudomonas aeruginosa, bacillus cereus, candida lipolytica, nitrifying bacteria and paracoccus denitrificans. By adopting the industrial sewage treatment agent disclosed by the invention, the removal rate of sewage suspension solids can be up to 99.8%, the biochemical oxygen demand (BOD) can be up to 98.7%, the chemical oxygen demand (COD) removal rate can be up to 98%, the industrial sewage treatment agent is less in sludge amount, free of secondary pollution, stable in treatment effect, environment-friendly, and non-toxic.
