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, polyethylene glycol, fatty amine, hydroxypropyl methyl cellulose sodium, polyaluminum chloride, polyacrylamide, zinc oxide, bentonite and waterto obtain modified polyacrylamide; obtaining modified glass fibers by adopting titanium dioxide, germanium oxide, boron oxide and gallium oxide; and mixing the modified polyacrylamide, the modified glass fibers, diatomite, hydroxymethyl acrylamide, methyl methoxybenzoate, glyceryl stearate and an auxiliary additive for 30 minutes to 40 minutes under the temperature condition of 70 DEG C-80 DEG Cand the pressure condition of 30 MP-40 MPa, and relieving pressure and cooling to obtain the sewage treatment agent. The sewage treatment agent obtained by the invention can be used for efficiently treating domestic sewage or industrial sewage and removing organic pollutants and harmful microorganisms in the 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...
