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 and comprehensive methods to deal with the pollution of water resources, but most of the physical methods have the problem 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

Abstract

The invention provides a sewage treatment agent and a use method thereof, wherein the sewage treatment agent comprises: diatomaceous earth, 5-10 parts of lithopone, sodium silicate, ferric chloride, bentonite, alum, aluminum sulfate, aluminum chloride, sodium carbonate, sodium chloride, lime, sodium carbonate, sodium polyacrylate and an adsorbate. According to the present invention, with the sewage treatment agent, the treated wastewater is almost colorless and transparent, and can meet the requirements of the national sewage comprehensive discharge standard; and the sewage treatment agent hascharacteristics of complete treatment, low treatment cost, no toxicity, and no pollution.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment agent and a use method. 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 wat...
