Domestic sewage purifying agent and preparation method thereof

Abstract

The invention discloses a domestic sewage purifying agent and a preparation method thereof, wherein the domestic sewage purifying agent is prepared from the following components in parts by weight: 40 parts of diatomite, 20-50 parts of silica powder, 15-35 parts of a gypsum powder, 1-9 parts of ferrous chloride, 2-6 parts of sodium carbonate, 2-8 parts of an aluminum oxide powder, 1-5 parts of thiobacillus denitrificans, 3-7 parts of bacillus licheniformis, 1-7 parts of sodium carboxymethylcellulose, 30-50 parts of polyvinyl alcohol, and 0.01-0.05 part of Tween 80. Compared with the prior art, the obtained domestic sewage purifying agent and the preparation method thereof have the advantages of simple process and low cost, not only have the effect of a sewage purifying agent of the prior art, but also have strong purification effect of domestic sewage, and can greatly save the amount.

Description

technical field [0001] The invention relates to a domestic sewage purifying agent and a preparation method thereof, belonging to the technical field of domestic sewage purification. Background technique [0002] Domestic sewage is the sewage produced in the process of human life, and it is one of the main pollution sources of water bodies, mainly feces and washing sewage. The amount of domestic sewage discharged by each person in the city is 150-400L per day, which is closely related to the living standard. Domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugar and fatty protein; it also often contains pathogenic bacteria, viruses and parasite eggs; inorganic salts such as chloride, sulfate, phosphate, bicarbonate and sodium, Potassium, calcium, magnesium, etc. The general feature is high nitrogen, sulfur and phosphorus content, and the post-processing is relatively difficult. People should protect water resources. China's national con...
