Abstract

The invention discloses a treatment agent of domestic sewage, prepared from the following raw materials in parts by weight: 5-15 parts of attapulgite, 4-12 parts of ferric chloride, 24-38 parts of coal gangue, 14-24 parts of montmorillonite, 6-10 parts of polyacrylamide, 10-16 parts of straw, 8-15 parts of starch, 2-5 parts of activated carbon, 18-30 parts of modified diatomite and 0.5-4 parts of cucurbitacin. The invention also discloses a preparation method of the chemical. The treatment agent of domestic sewage has broad sources of raw materials, low cost of raw materials, a simple preparation process, low equipment investment cost and applicability to large-scale industrial production; the cucurbitacin, straw, coal gangue, modified diatomite and other components in the treatment agent play a synergetic effect; and the treatment agent has low dosage, good treatment effect, stable performance and good quality of effluent water, reduces the cost of water treatment and has good economic benefit and social benefit.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to a domestic sewage treatment agent. Background technique [0002] Domestic sewage is mainly various detergents used in urban life, sewage, garbage, feces, etc., mostly non-toxic inorganic salts. Domestic sewage contains a lot of nitrogen, phosphorus, sulfur, and many pathogenic bacteria. 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. With the acceleration of urbanization and industrializa...
