Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the examples.

[0013] The sewage treatment agent is configured by the following parts by weight ratio, and is characterized in that: polyaluminum chloride 23; polyacrylamide 23; polyethyleneimine 10; bentonite 25.

[0014] The relative density of the polyferric trichloride is 1.450, acidic and easily soluble in water. Compared with the serious harm caused by aluminum salt flocculant residual aluminum to the human body and the biological toxicity of aluminum, as well as the poor coagulation effect and poor product stability of iron salt flocculant, this chemical composition has a wide range of applicable pH values. After treatment, the pH of the water does not decrease much, the chroma of the water does not increase, and the treatment effect is excellent. The effect is more pronounced when the treated water temperature is lower.

Abstract

The present invention relates to a chemical reagent, specifically to a novel sewage treatment agent in the field of sewage treatment, wherein the sewage treatment agent is prepared from the following components by weight: 10-25 parts of polyaluminium chloride, 20-25 parts of polyacrylamide, 7-12 parts of polyethyleneimine, and 20-25 parts of bentonite. According to the present invention, the selected polyaluminium chloride is easily dissolved in water, and has characteristics of excellent coagulation effect, good product stability and wide pH value application range, wherein the reduction of the pH value of the treated water is not high; the inorganic matter component and the organic matter component are synergistically adopted as the co-coagulation agent, such that the sewage treatment agent of the present invention has the excellent flocculation effect; and the sewage treatment agent has advantages of rapid purification, good effect, environmental protection, no toxicity, and the like.

Description

technical field [0001] The invention relates to a chemical reagent, in particular to a novel sewage treatment agent for sewage treatment. 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 treat sewage, ...
