Abstract

The invention discloses a high efficiency sewage treatment agent used for treating domestic sewage. The high efficiency sewage treatment agent used for treating domestic sewage comprises, by weight, 17 to 21 parts of poly aluminum ferrous chloride, 13 to 17 parts of sodium lignosulfonate, 25 to 30 parts of polyacrylamide, 3 to 6 parts of ferrous sulphate, 8 to 12 parts of chitosan, 6 to 10 parts of calcium chloride, 2 to 5 parts of berberine, and 35 to 40 parts of modified sawdust. The invention also discloses a preparation method of the high efficiency sewage treatment agent used for treatingdomestic sewage. The high efficiency sewage treatment agent used for treating domestic sewage possesses excellent treatment effect on domestic sewage, is capable of reducing COD, BOD, SS, total phosphor, total nitrogen, and ammonia nitrogen in domestic sewage, satisfying requirements of market on sewage treatment agent, and is promising in market prospect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an efficient sewage treatment agent for treating domestic sewage and a preparation method thereof. Background technique [0002] With the continuous development of industry, the use of water resources has also increased, but there is less than 1% of fresh water on the earth and only about 0.007% of which can be directly used by humans. Therefore, saving water resources and reusing water Resources become the focus of attention. In the reuse of water resources, sewage treatment is the top priority. [0003] The development and progress of my country's sewage treatment industry is relatively late. Since the founding of the People's Republic of China and before the reform and opening up, the demand for my country's sewage treatment is mainly for industrial and national defense cutting-edge applications. After the reform and opening up, the rapid development of the national...
