Abstract

The invention discloses an efficient sewage treating agent specially used for sanitary sewage. The efficient sewage treating agent specially used for sanitary sewage is prepared from, by weight, 25-30 parts of polyacrylamide, 3-6 parts of chitosan, 2-5 parts of aluminium potassium sulfate dodecahydrate, 4-7 parts of activated carbon, 12-15 parts of polyethyleneimine, 2-4 parts of ferrous sulfate, 1-3 parts of sodium citrate, 16-19 parts of perlite, 10-13 parts of soapstone and 3-5 parts of starch xanthate. The invention also discloses a preparing method of the efficient sewage treating agent specially used for sanitary sewage. The prepared sewage treating agent has a good treating effect on sanitary sewage and has good stability. The product can meet the requirements of the market on sanitary sewage treating products, and the index of the treated sanitary sewage can reach the national emission standard.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency sewage treatment agent for domestic sewage and a preparation method thereof. Background technique [0002] China's per capita water resources are small and the spatial distribution is uneven. With the acceleration of urbanization and industrialization in China, the demand gap for water resources is also increasing. In this context, the sewage treatment industry has become an emerging industry, and it is in the same important position as the tap water production, water supply, drainage, and reclaimed water reuse industries. [0003] Domestic sewage is the sewage produced in the process of human life, and it is one of the main pollution sources of water bodies. 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 contai...
