Embodiment 1

[0018] The bacterial agent for industrial sewage treatment of the present invention comprises the following components by weight ratio: 12 parts of polyacrylamide, 10 parts of silicon dioxide, 4 parts of persulfate, 2 parts of sodium carbonate and 18 parts of composite microorganisms.

[0019] Among them, the composite microorganisms include Bacillus licheniformis, Pseudomonas aeruginosa, Bacillus cereus, Candida lipolytica, nitrifying bacteria, and Paracoccus denitrificans.

[0020] Composite microorganisms are prepared through the following steps:

[0021] (1) Each strain was activated and expanded; the culture medium was: yeast extract 1%, peptone 1.5%, glucose 0.5%, NH 4 Cl 2 0.5%, K 2 HPO 4 0.5%, the balance is water, and the medium is sterilized at 121°C for 20 minutes.

[0022] (2) The expanded strains were inoculated into the mixed culture medium with the following volume percentages: 2% of Bacillus licheniformis, 3% of Pseudomonas aeruginosa, 2% of Bacillus cereus...

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.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an industrial sewage treatment bacterial agent. Background technique [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 environment die, causing the water body to lose its self-purification ability, and the chemical composition of the sewage treatment agent is too high to cause secondary pollution. 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 by the present invention. Contents of the invention [000...
