Sewage treating solvent

Abstract

The invention relates to a sewage treating solvent. The sewage treating solvent is prepared from, by weight, 10-30 parts of diszolidinyl urea, 5-15 parts of methylisothiazolinone, 10-15 parts of medical stone particles, 20-30 parts of sodium lignin sulfonate, 10-20 parts of chitosan, 10-20 parts of polyvinylpyrrolidone, 10-20 parts of polymeric aluminum sulfate-silicate, 10-20 parts of diacetone acrylamide, 10-20 parts of phosphonate, 10-20 parts of ethylenediamine tetra methylenephosphonic acid and 50-100 parts of deionized water. By controlling and changing the adding sequence of inorganic polymer matter and organic polymer matter with different functional groups and reaction occurrence and nonoccurrence conditions in the recombination process, the purposes of good form distribution and stability of the components before feeding and rapid form conversion and efficient coagulation and flocculability of the components after feeding are achieved.

Description

technical field [0001] The invention relates to a sewage treatment solvent. 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] There are many methods of sewage treatment, but the common ones are physical and chemical. Among them, chemical treatment of sewage is the most widely used. 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. ...

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

[0005] 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
