Abstract

The invention relates to the technical field of sewage treatment agents and specifically relates to a domestic sewage treatment agent and a preparation method thereof. The domestic sewage treatment agent comprises the following raw materials in parts by weight: 10-20 parts of ferric trichloride, 5-8 parts of ferrous sulfate, 5-8 parts of magnesium sulfate, 3-5 parts of polyacrylamide, 10-20 parts of caustic soda flakes, 20-35 parts of modified lignin sulfonate, 10-15 parts of starch xanthate, 20-30 parts of modified diatomite, 15-20 parts of cross-linked rectorite and 1-5 parts of chitosan-graphene composite material. The domestic sewage treatment agent provided by the invention is capable of continuously treating high-concentration domestic sewage under the coordination action of the compounded raw materials; in the meantime, the contents of COD (Chemical Oxygen Demand), BOD (Biological Oxygen Demand) and SS (Suspended solids) in the treated domestic sewage are obviously reduced; the treated water can be recycled repeatedly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage treatment agent and a preparation method thereof. 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. People ...
