Abstract

The invention relates to a sewage purification material and a preparation method thereof. The sewage purification material is prepared from modified polyacrylate, a modified ferroferric oxide precursor, ethanol and water, wherein the modified polyacrylate is prepared by enabling polyacrylate, polyethylene glycol 600, isotridecyl alcohol, polyethylene glycol 400 and aluminum trichloride to be subjected to a reaction; the polyacrylate is prepared by enabling acrylic acid, acrylamide, water, benzoyl peroxide, hexanedioxane, Span 60, dichloroethane, polyvinyl alcohol 1788 and N, N-methylenebisacrylamide to be subjected to a reaction; the modified ferroferric oxide precursor is prepared by enabling a ferroferric oxide precursor, polyaluminum chloride, the ethanol and polyethylene glycol 600 tobe subjected to a reaction; the ferroferric oxide precursor is prepared by enabling ferric trichloride, formic acid, water, the ethanol and polyethylene glycol 1000 to be subjected to a reaction. Thesewage purification material provided by the invention has excellent water chemical oxygen demand (COD) reduction performance and can be recycled.

Description

technical field [0001] The invention relates to the field of water body purification, in particular to a sewage purification material and a preparation method thereof. Background technique [0002] With the rapid development of the country's economy and industrialization, environmental pollution has been paid more and more attention by the country, especially water pollution, which will seriously affect people's living environment and health, and the governance of water pollution needs to be solved urgently. Therefore, the state encourages researchers in different fields to conduct research on efficient treatment methods for polluted water bodies. Due to the low treatment efficiency of ordinary sewage purification materials for reducing COD performance in polluted water bodies. Therefore, purification materials for sewage need to be improved in terms of highly efficient COD reduction in water. Contents of the invention [0003] The purpose of the present invention is to ...
