Abstract

The invention discloses a treatment agent for domestic wastewater, wherein the treatment agent is composed of the following raw materials in parts by weight: 12-18 parts of kaolin, 18-25 parts of diatomite, 6-14 parts of barite, 5-8 parts of a talcum powder, 9-18 parts of cross-linked rectorite, 4-8 parts of chitosan, 4-6 parts of starch xanthate, 2-4 parts of acorus calamus, 3-6 parts of bunge corydalis herb, 2-4 parts of cape jasmine, 1-4 parts of sodium hydroxypropyl methyl cellulose, 0.5-2 parts of triethanolamine, 0.5-3 parts of plant starch, and 10-15 parts of mineral waste residues. The invention also discloses a preparation method of the treatment agent. The prepared product is used for treating the domestic wastewater; through compounding of the raw materials, a coordinating role is played, flocculation, sedimentation, adsorption and sterilization effects can be improved, moreover, the cost of treatment can be greatly reduced, and the treatment agent has a wide application prospect and remarkable economic and social benefits.

Description

technical field [0001] The invention relates to the field of domestic sewage treatment, in particular to a treatment agent for domestic sewage. Background technique [0002] my country is one of the countries that lack water resources, especially the per capita water resources are about 2100m 3 , accounting for only 28% of the world's per capita water resources, the shortage of water resources has become one of the important factors restricting the sustainable development of the economic and social development. 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...
