Sewage processing agent

Abstract

The invention relates to a sewage processing agent, which comprises the following raw materials in parts by weight: 4 to 7 parts of bentonite, 2 to 4 parts of alum, 1 to 2 parts of aluminum sulfate, 5 to 10 parts of lithopone, 10 to 15 parts of sodium chloride, 0.3 to 1 part of lime, 10 to 20 parts of adsorbate, 0.5 to 1 part of sodium carbonate, 6 to 10 parts of iron chloride, and 40 to 50 parts of water. By controlling and changing the addition sequence of inorganic polymer and organic polymer with different functional groups and the conditions, under which reactions will or will not happen during the compounding process, the components can maintain good morphology distribution and stability before addition; after addition, the morphology of the components quickly changes, and the components carry out flocculation efficiently.

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. [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. I...

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
