Embodiment 1

[0014] A new type of water purifier, consisting of the following raw materials in parts by weight: 20 parts of sodium sulfate, 10 parts of polyacrylamide, 5 parts of sodium metasilicate pentahydrate and 20 parts of sodium phosphate; the preparation method of the water purifier includes The steps are as follows: respectively grind sodium sulfate, polyacrylamide, sodium metasilicate pentahydrate and sodium phosphate to 100 mesh, and mix well to obtain the water purifying agent.

[0015] When the novel water purifying agent of the present invention is used, only 0.1 ppm of the water purifying 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 new type of water purifier, consisting of the following raw materials in parts by weight: 40 parts of sodium sulfate, 20 parts of polyacrylamide, 15 parts of sodium metasilicate pentahydrate and 50 parts of sodium phosphate; the preparation method of the water purifier includes The following steps are as follows: respectively grind sodium sulfate, polyacrylamide, sodium metasilicate pentahydrate and sodium phosphate to 200 mesh, and mix well to obtain the water purifying agent.

[0018] When the novel water purifying agent of the present invention is used, only 2.0 ppm of the water purifying 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 new type of water purifying agent, consisting of the following raw materials in parts by weight: 30 parts of sodium sulfate, 15 parts of polyacrylamide, 10 parts of sodium metasilicate pentahydrate and 40 parts of sodium phosphate; the preparation method of the sewage treatment agent includes the following Steps: respectively pulverize sodium sulfate, polyacrylamide, sodium metasilicate pentahydrate and sodium phosphate to 120 mesh, and mix evenly to obtain the water purifying agent.

[0021] When the novel water purifying agent of the present invention is used, only 1.0 ppm of the water purifying 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 water purifying 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 cont...

Abstract

The invention relates to a chemical reagent, in particular to a novel water purifying agent for sewage treatment. The novel water purifying agent is prepared from, by weight, 20-40 parts of sodium sulfate, 10-20 parts of polyacrylamide, 5-15 parts of sodium metasilicate pentahydrate and 20-50 parts of sodium phosphate. Polyacrylamide used in water purifying agent is easily dissolved in water and excellent in coagulate effect, the product stability is good, the applicable pH value range is wide, the pH of water treated with the water purifying agent is hardly reduced, at the same time, inorganic ingredients and organic ingredients are synergized to serve as a coagulant, and the water purifying agent is excellent in flocculation effect and has the advantages of being rapid in purification speed, good in effect, environmental friendly, free of toxins and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a water purifying 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 t...
