Problems solved by technology

[0004] The water treatment agent mainly used now has a single function, so various agents such as flocculants, corrosion inhibitors, and fungicides must be added to the water treatment system. Large, expensive, and various reagents will resist each other through various chemical reactions, resulting in reduced efficacy

Abstract

The invention relates to the technical field of water treatment agents and particularly relates to a multifunctional sewage treatment agent. The multifunctional sewage treatment agent comprises the following raw materials in parts by weight: 10-20 parts of sepiolite powder, 30-40 parts of bentonite, 30-40 parts of starch xanthate, 0.1-0.5 part of sodium hydroxide caustic soda, 1-5 parts of polyaspartic acid, 0.1-0.5 part of amino trimethylene phosphonic acid, 25-50 parts of cross-linked rectorite, 20-50 parts of aluminum polychlorid, 5-30 parts of chitosan and 10-30 parts of deionized water. The multifunctional sewage treatment agent provided by the invention is high in purity, free of impurity and dustless, the aqueous solution is clear, transparent, non-toxic and free of effect on operation workers, and the treated water is free of problems such as secondary pollution.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multifunctional sewage treatment agent and a preparation method thereof. Background technique [0002] my country is a country with a shortage of water resources. The per capita water resources are only 1 / 4 of the world's, and the distribution of water resources is seriously uneven. How to alleviate the shortage of water resources and pollution has become an urgent problem. In order to solve the problem of water shortage, in addition to increasing sources of income, reducing expenditure, and comprehensive utilization, pollution control has gradually become one of the basic principles that our country must adhere to for a long time. [0003] At present, there are many methods to deal with the pollution of water resources, such as physics, chemistry, biology and synthesis. The physical method is to recover the insoluble suspended pollutants in the sewage through physica...
