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: using dimethyl diallyl ammonium chloride, acrylamide, ethylenediaminetetraacetic acid, polypropylene alcohol, fatty amine, sodium hydroxymethyl cellulose, polyaluminum chloride, Polyacrylamide, strontium oxide and bentonite and water to obtain modified polyacrylamide; titanium dioxide, calcium oxide, barium oxide, magnesium oxide, tellurium oxide, boron oxide, silicon oxide to obtain modified glass fiber; will include modified polyacrylamide , Modified glass fiber raw materials are mixed to obtain a sewage treatment agent. The sewage treatment agent obtained by the invention can efficiently treat domestic sewage or industrial sewage and remove organic pollutants and harmful microorganisms therein.

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...
