Abstract

The invention discloses a domestic sewage treatment agent. The domestic sewage treatment agent comprises, by weight, 25-40 parts of sodium polyacrylate, 11-15 parts of montmorillonite, 10-20 parts ofsweet potato starch, 5-11 parts of potassium carbonate, 5-10 parts of tobermorite, 6-12 parts of water glass, 2-5 parts of sodium borate, 1-6 parts of lotus leaf powder, 2-5 parts of chestnut shell powder, 40-60 parts of washing water of rice, 5-10 parts of tea seed cake powder and 1-5 parts of mirabilite. The raw materials of the domestic sewage treatment agent are easy to obtain, are environmentally friendly and safe, and are compounded to achieve coordinating effects, so the treatment agent can continuously treat high-concentration domestic sewage, obviously reduces the COD, BOD and SS of treated domestic sewage, and has a wide application range; and the treatment agent also has the advantages of simple preparation method and treatment technology, good treatment effect, stable performances, good quality of the effluent water, and effective reduction of the cost of water treatment.

Description

technical field [0001] The invention relates to the field of life, in particular to a domestic sewage treatment agent and a preparation method thereof. Background technique [0002] Sewage produced in the process of human life is one of the main sources of water pollution. 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 under the action of anaerobic bacteria, it is easy to generate odorous substances. The development and progress of my country's sewage treatment industry is relatively late. Since the founding of the Peopl...
