Embodiment 1

[0014] A novel sewage treatment agent is composed of the following raw materials in parts by weight: 20 parts of sodium sulfate, 10 parts of polyacrylamide, 5 parts of aluminum chloride and 20 parts of diatom mud; the preparation method of said sewage treatment agent comprises the following steps : Respectively crush sodium sulfate, polyacrylamide, aluminum chloride and diatom mud to 100 mesh, and mix evenly to obtain the sewage treatment agent.

[0015] When the novel 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 novel sewage treatment agent is composed of the following raw materials in parts by weight: 40 parts of sodium sulfate, 20 parts of polyacrylamide, 15 parts of aluminum chloride and 50 parts of diatom mud; the preparation method of said sewage treatment agent comprises the following steps : Respectively crush sodium sulfate, polyacrylamide, aluminum chloride and diatom mud to 200 mesh, and mix evenly to obtain the sewage treatment agent.

[0018] When the novel 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 novel sewage treatment agent is composed of the following raw materials in parts by weight: 30 parts of sodium sulfate, 15 parts of polyacrylamide, 10 parts of aluminum chloride and 40 parts of diatom mud; the preparation method of said sewage treatment agent comprises the following steps: Sodium sulfate, polyacrylamide, aluminum chloride and diatom mud are respectively crushed to 120 mesh, mixed evenly, and the sewage treatment agent is obtained.

[0021] When the novel 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.

[0022] The novel sewage treatment agent obtained in the embodiment of the present invention 1-3 is used to treat the sewage of a certain sewage treatment plant, and the control index of the sewage before and...

Abstract

The invention relates to a chemical reagent, specifically to a novel sewage treating agent on the aspect of sewage treatment. The novel sewage treating agent is prepared from the following raw materials in parts by weight: 20-40 parts of sodium sulfate, 10-20 parts of polyacrylamide, 5-15 parts of aluminium chloride and 20-50 parts of diatom ooze. The novel sewage treating agent overcomes the shortcomings in the existing sewage treatment methods; polymerization ferric chloride selected by the sewage treating agent can be dissolved in water easily, so that excellent coagulation effect, high product stability, wide applicable pH value range, and low pH reduction of water after treatment are achieved; meanwhile, inorganic substances and organic substances are synergistically adopted as a coagulant, so that the novel sewage treating agent achieves an excellent flocculation effect; and in addition, the novel sewage treating agent has the advantages of high purification speed, good effect, environment protection, no toxic, and the like.

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 ...
