Sewage treatment agent

Abstract

The invention relates to a sewage treatment agent which is prepared from the following ingredients in parts by weight: 20-30 parts of polyacrylamide, 12-15 parts of polyethylene imine, 20-25 parts of activated carbon, 5-10 parts of lithopone, 10-15 parts of sodium chloride, 0.3-1 part of lime, 10-20 parts of adsorbate, 0.5-1 part of sodium carbonate, 6-10 parts of ferric chloride and 40-50 parts of water. Through controlling and changing the addition sequence of inorganic macromolecule substances and organic macromolecule substances of different functional groups and conditions for generating reaction or not generating reaction during a recombination process, such ingredients are kept in favorable shape distribution and stability before being fed, and such ingredients have rapid shape conversion and efficient coagulation and flocculation properties after being fed.

Description

technical field [0001] The invention relates to a sewage treatment agent. 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. my country is also facing these problems. my country is a country with scarce water resources. How to alleviate the shortage of water resources and pollution has become an urgent problem. [0003] There are many methods of sewage treatment, but the common ones are physical and chemical. Among them, chemical treatment of sewage is the most used by people. Polyacrylamide is the most commonly used water treatment agent in chemical methods. The application of polyacrylamide in the water treatment industry mainly includes three aspects: raw water treatment, sewage treatment and industrial water treatment. In raw wa...

AI Technical Summary

Problems solved by technology

Although polyacrylamide plays a very important role in water treatment, the existing methods generally use a single polyacrylamide, which is expensive and inhibits its wider application.

Secondly, 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, but the existing sewage treatment agents have secondary pollution problems in their reagent components, which will also have a certain impact on the environment
