Problems solved by technology

After physical and chemical treatment, the sludge is dehydrated and filtered to become semi-dry sludge with a moisture content of about 80%. Since the semi-dry sludge contains harmful substances such as heavy metals, it is finally transported to landfill, although the water quality has improved. Purification, but the pollution is transferred to the sludge, directly causing serious pollution to soil and groundwater resources

Abstract

The invention discloses a treatment chemical for treating domestic sewage and a preparation method of the treatment chemical. The treatment chemical for treating the domestic sewage is prepared from the following raw materials in parts by weight: 14 to 19.5 parts of maleic acid-acrylic acid copolymer, 5.6 to 7.5 parts of steel residues, 6 to 9.6 parts of beewax, 8 to 12 parts of acrylic emulsion,4 to 7.2 parts of plant starch, 6 to 8.8 parts of chitosan, 3.4 to 5.2 parts of hydroxymethyl cellulose, 3.8 to 4.6 parts of dodecyl dimethyl tertiary amine, 1.5 to 2.4 parts of chloramphenicol, 5 to6.6 parts of cactus, and 14 to 18.5 parts of glycerol. Different raw materials are prepared into different products by adopting different preparation processes, then the different products are mixed,various products are in synergistic effect, and a prepared finished product has good treatment effect for domestic sewage; and by adopting the steel residues, chitosan and the like, no aluminum salt water purifier is adopted, and the loss of the aluminum ore can be reduced.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a treatment agent for treating domestic sewage. Background technique [0002] Cities, also called urban settlements, are larger settlements formed by the agglomeration of non-agricultural industries and non-agricultural populations. A densely populated area is called a city, which generally includes residential areas, industrial areas, and commercial areas and has administrative jurisdiction. The administrative jurisdiction function of a city may involve a wider area than itself, including residential areas, streets, hospitals, schools, public green spaces, office buildings, commercial stores, squares, parks and other public facilities. [0003] A lot of waste is produced in the city every day, and domestic sewage is one of them. Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings, such as residences, ins...
