Description

technical field [0001] The invention relates to a treatment device, in particular to a domestic sewage treatment device. Background technique [0002] Domestic sewage is mainly the discharge water produced by various kitchen water, washing water and toilet water used in human life. Most of them are non-toxic inorganic salts. Domestic sewage contains a lot of nitrogen, phosphorus and sulfur, and there are many pathogenic bacteria. Sewage produced in the process of human life is one of the main sources of water pollution. Mainly feces and washing sewage. 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...
