Problems solved by technology

Domestic sewage is a kind of sewage with an increasing proportion in today's society, which has a great impact on the natural environment and human life. The content of nitrogen, phosphorus and oil in domestic sewage is high. Traditional physical methods and chemical agents, It often consumes a lot of manpower and material resources, and the effect is not obvious. The use of a large amount of chemical agents will also cause a burden on the environment.

Abstract

The invention provides a sewage treatment agent and a preparation method thereof and belongs to the technical field of sewage treatment. The sewage treatment agent is composed of polyacrylamide, citric acid, corn starch, coke slag powder, activated carbon, sodium alginate, lactic acid bacteria, actinomycetes, saccharomycetes, bifidobacteria, photosynthetic bacteria, bacillus and indigenous bacteria. The sewage treatment agent has a fast reaction rate, does not produce toxic substances during the reaction process, realizes ecological and resource sewage treatment, is free of a sludge treatmentsystem, prevents secondary pollution and has stable treatment effects.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment agent and a preparation method thereof. Background technique [0002] With the continuous development of society, the use of water resources also increases, and there is less than 1% of fresh water on the earth, and only about 0.007% of it can be directly used by human beings. Therefore, saving and reusing water resources Resources have become the focus of attention. In the reuse of water resources, sewage treatment is the top priority. Domestic sewage is a kind of sewage with an increasing proportion in society, which has a great impact on the natural environment and human life. The nitrogen, phosphorus and oil content in domestic sewage are relatively high. Traditional physical methods and chemical agents, It often consumes a lot of manpower and material resources, and the effect is not obvious. The use of a large number of chemicals will also cause...
