Sewage treating agent and preparation method thereof

Abstract

The invention discloses a sewage treating agent and a preparation method thereof. The preparation method comprises the following steps: firstly, preparing a star polymer by taking sodium acrylate andacrylamide as monomers and dihydroxyl diperiodiate potassium cuprate (III) as an initiator, then according to the weight parts, adding 20 parts of starch into 1000 parts of water, gelatinizing at 78-83 DEG C, then cooling the temperature to 50-55 DEG C, sequentially adding 1-1.3 parts of sodium hydroxide, 3-6 parts of cellulose, 10-12 parts of star polymer prepared in the S1, 6-8 parts of crylic acid, 18-23 parts of acrylamide, 0.35-0.38 parts of ammonium persulfate and 0.19-0.21 part of sodium sulfite, stirring for 20-30min, then adding 2-3 parts of an inorganic flocculant, and 0.032-0.045 part of N,N- methacrylamide, stirring for 30min and stopping reaction, then drying and grinding to obtain a sewage treatment agent. The prepared sewage treatment agent has the characteristics of fast flocculation speed, and low biodegradability and toxicity.

Description

technical field [0001] The invention relates to a sewage treatment agent and a preparation method thereof. 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. Our country is also facing these problems. Our country is a country with insufficient water resources and medical resources. How to alleviate the problems of water resource medical shortage and pollution has become an urgent problem. [0003] 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 sewa...

Problems solved by technology

[0003] 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, but the existing sewage treatment agents have secondary pollution problems in their reagent components, which will also have a certain impact on the environment

Inorganic flocculant composite polymer has become the most researched flocculant at present. It has the characteristics of good flocculation effect and low toxicity, but the flocculation speed of the polymer part is slow, which leads to the unsatisfactory flocculation effect of the composite.
