Abstract

The invention provides a sewage treatment agent and a preparation method thereof. The preparation method of the sewage treatment agent comprises the following steps: adopting dimethyl diallyl ammoniumchloride, acrylamide, ethylenediamine tetraacetic acid, polypropylene glycol, fatty amine, carboxymethyl cellulose sodium, polyaluminum chloride, polyacrylamide, strontium oxide, bentonite and waterto obtain modified polyacrylamide; obtaining modified microcrystalline glass fibers by adopting titanium dioxide, potassium oxide, manganese oxide, boron oxide, calcium oxide, aluminum oxide and silicon oxide; and mixing the modified polyacrylamide, the modified microcrystalline glass fiber, diatomite, hydroxymethyl acrylamide, methyl methoxybenzoate, glyceryl stearate, trimethylammonium acetate,ammonium persulfate, hydroxypropyl starch sodium phosphate, 2-mercaptobenzothiazole, 1-vinyl imidazole and sodium dodecyl benzene sulfonate to obtain the sewage treatment agent. The sewage treatment agent obtained by the method can be used for efficiently treating domestic sewage or industrial sewage.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment agent and a preparation method thereof. Background technique [0002] With the improvement of people's living standards in our country and the rapid acceleration of the urbanization process, the growth rate of various wastewater such as industrial wastewater and domestic sewage is astonishing, and the amount is huge. According to incomplete statistics, the industrial wastewater with high heavy metal content produced in my country every year amounts to hundreds of millions of tons. The organic pollutants and heavy metals in these industrial wastewater, such as phenols, dyes, cadmium, chromium, mercury, etc., are often highly toxic. Therefore, The water environment in the area is seriously polluted, causing damage and threat to the local environment. Although domestic sewage has a small content of heavy metals, when it is discharged into rivers and lakes...
