Embodiment 1

[0014] A sewage treatment agent, consisting of the following raw materials in parts by weight: 20 parts of trisodium phosphate, 10 parts of polyacrylamide, 5 parts of sodium lignosulfonate and 20 parts of bentonite; the preparation method of the sewage treatment agent comprises the following steps : respectively pulverize trisodium phosphate, polyacrylamide, sodium lignosulfonate and bentonite to 100 mesh, and mix evenly to obtain the sewage treatment agent.

[0015] When the sewage treatment agent of the present invention is used, only 0.1 ppm of the sewage treatment agent needs to be added to the sewage to be treated to obviously improve the sedimentation effect. Moreover, the COD and chromaticity indicators of the treated water will also be significantly improved.

Embodiment 2

[0017] A sewage treatment agent, consisting of the following raw materials in parts by weight: 40 parts of trisodium phosphate, 20 parts of polyacrylamide, 15 parts of sodium lignosulfonate and 50 parts of bentonite; the preparation method of the sewage treatment agent comprises the following steps : respectively pulverize trisodium phosphate, polyacrylamide, sodium lignosulfonate and bentonite to 200 mesh, and mix evenly to obtain the sewage treatment agent.

[0018] When the sewage treatment agent of the present invention is used, only 2.0 ppm of the sewage treatment agent needs to be added to the sewage to be treated to obviously improve the sedimentation effect. Moreover, the COD and chromaticity indicators of the treated water will also be significantly improved.

Embodiment 3

[0020] A sewage treatment agent, consisting of the following raw materials in parts by weight: 30 parts of trisodium phosphate, 15 parts of polyacrylamide, 10 parts of sodium lignosulfonate and 40 parts of bentonite; the preparation method of the sewage treatment agent comprises the following steps: Separately grind trisodium phosphate, polyacrylamide, sodium lignosulfonate and bentonite to 120 mesh, and mix evenly to obtain the sewage treatment agent.

[0021] When the sewage treatment agent of the present invention is used, only 1.0 ppm of the sewage treatment agent needs to be added to the sewage to be treated to obviously improve the sedimentation effect. Moreover, the COD and chromaticity indicators of the treated water will also be significantly improved.

Abstract

The invention relates to a chemical reagent, in particular to a novel sewage treatment agent for sewage treatment. The sewage treatment agent is composed of the following raw materials by weight: 20-40 parts of trisodium phosphate, 10-20 parts of polyacrylamide, 5-15 parts of sodium lignin sulfonate, and 20-50 parts of bentonite. The sewage treatment agent provided by the invention selects water-soluble polyferric chloride, has good coagulation effect, good product stability and wide pH application range, after treatment, the water pH decreases little, and inorganic matters and organic matters are used collaboratively as a coagulant, so that the sewage treatment agent provided by the invention has excellent flocculation effect. The sewage treatment agent has the advantages of rapid purification speed, good effect, environmental protection and no toxicity, etc.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage treatment agent and its application. 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] 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 ...
