Problems solved by technology

[0004] At present, there are many methods to deal with water resource pollution, such as physical, chemical, biological, and comprehensive methods, but most of the physical methods have problems of poor treatment effect and unstable treatment rate; biological methods are too expensive to be popularized and used; Chemical methods are used to treat sewage, but the existing water purifiers have secondary pollution problems in their reagent components, which will also have a certain impact on the environment

Embodiment 1

[0014] A novel water purifying agent is composed of the following raw materials in parts by weight: 20 parts of aluminum sulfate, 10 parts of polyacrylamide, 5 parts of sodium silicate and 20 parts of oxalic acid; the preparation method of said water purifying agent comprises the following steps: Crush aluminum sulfate, polyacrylamide, sodium silicate and oxalic acid to 100 mesh, and mix well to obtain 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 novel water purifying agent is composed of the following raw materials in parts by weight: 40 parts of aluminum sulfate, 20 parts of polyacrylamide, 15 parts of sodium silicate and 50 parts of oxalic acid; the preparation method of said water purifying agent comprises the steps of: Crush aluminum sulfate, polyacrylamide, sodium silicate and oxalic acid to 200 mesh, mix well, and obtain 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 novel water purifying agent is composed of the following raw materials in parts by weight: 30 parts of aluminum sulfate, 15 parts of polyacrylamide, 10 parts of sodium silicate and 40 parts of oxalic acid; the preparation method of the sewage treatment agent comprises the following steps: respectively Aluminum sulfate, polyacrylamide, sodium silicate and oxalic acid are pulverized to 120 mesh and mixed evenly to obtain 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 control index of the sewage before and after th...

Abstract

The invention relates to a chemical agent, in particular to a novel water purifying agent for sewage treatment. The novel water purifying agent is composed of, by weight, 20-40 parts of sodium sulfate, 10-20 parts of polyacrylamide, 5-15 parts of sodium silicate and 20-50 parts of sodium chloride. According to the novel water purifying agent, the selected polyacrylamide has the advantages of being capable of being easily dissolved in water, excellent in coagulation effect, good in product stability and the like. The pH value applicable range of the novel water purifying agent is wide, and the pH value of water is hardly lowered after treatment; and meanwhile, inorganic components and organic components are cooperatively used as flocculating agents, so that the novel water purifying agent has an excellent flocculent effect. The novel water purifying agent has the advantages of being high in purifying speed, good in effect, environmentally friendly, free of toxicity 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...
