Abstract

The invention discloses a domestic sewage treatment agent, and the treatment agent is prepared from the following raw materials in parts by weight: 15 to 25 parts of polyferric trichloride, 5 to 15 parts of polyferric sulfate, 10 to 15 parts of polyacrylamide, 15 to 25 parts of caustic soda flakes, 5 to 15 parts of activated carbon, 5 to 15 parts of zeolite powder, 5 to 15 parts of defoaming agents, 5 to 15 parts of surfactants and 5 to 15 parts of sodium alginate; the surfactant is fatty alcohol polyoxyethylene ether sodium sulfate (AES), and the defoaming agent is a polydimethylsiloxane emulsion defoaming agent. The invention also discloses a preparation method of the domestic sewage treatment agent. The treating agent disclosed by the invention can be used for effectively treating domestic sewage of residents, the treating effect is good, the cost is lower, the performance is more stable, and treated pollution reaches the national sewage discharge standard.

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 the discharge water produced by various kitchen water, washing water and toilet water used in human life, and most of them are non-toxic inorganic salts. Sewage produced in the process of human life is one of the main sources of water pollution. Mainly feces and washing sewage. 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. At present, there are ma...
