Abstract

The invention discloses a preparation method of a domestic sewage treatment agent. Through treatment on a plurality of biological raw materials and then mixing of the biological raw materials and other auxiliary agents, the domestic sewage treatment agent is prepared. The preparation method can be operated simply. The domestic sewage treatment agent has a low cost and good effects and is suitable for large scale production. The domestic sewage treatment agent has a domestic sewage suspension removal ratio of 95% or more, a BOD removal ratio of 90% or more and a COD removal ratio of 90% or more.

Description

technical field [0001] The invention relates to the technical field of domestic wastewater treatment, in particular to a preparation method of a domestic wastewater treatment agent. Background technique [0002] 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. The existing domestic sewage treatment materials include polyferric sulfate, which is an inorganic polymer coagulant water purification material developed on the basis of the coagulation and hydrol...
