Novel sewage treatment agent

Abstract

The invention relates to a chemical reagent and especially relates to a novel sewage treatment agent and belongs to the field of sewage treatment. The novel sewage treatment agent comprises, by weight, 25 to 40 parts of polyferric chloride, 10 to 15 parts of polyacrylamide, 7 to 12 parts of polymine and 28 to 43 parts of bentonite. The polyferric chloride can be dissolved in water easily and has excellent coagulation effects and good product stability. The novel sewage treatment agent has a wide pH application range. A pH value of water treated by the novel sewage treatment agent is reduced slightly. Through utilization of an inorganic-organic component mixture as a coagulant, excellent coagulation effects are obtained. The novel sewage treatment agent has the advantages of fast purification rate, good effect, environmental benefits and no toxicity.

Description

technical field [0001] The invention relates to a chemical reagent, in particular to a novel sewage treatment agent for sewage treatment. Background technique [0002] Due to population growth and economic development, a series of problems affecting the quality of resources caused by excessive exploitation and irrational development and utilization of resources have directly threatened the survival of us and future generations. [0003] Our country is also facing these problems. Our country is a country with scarce water resources. How to alleviate the shortage of water resources and pollution has become an urgent problem. [0004] At present, there are physical, chemical, biological, comprehensive and other methods to deal with the pollution of water resources, but most of the physical methods have problems of poor treatment effect and unstable treatment rate; the cost of biological methods is too high to be popularized and used; Chemical methods are used to treat sewage, ...
