Abstract

The invention belongs to the technical field of sewage treatment agents, and in particular relates to an oil-containing wastewater treatment agent and a preparation method thereof. The oil-containing wastewater treatment agent disclosed by the invention comprises the following raw materials in parts by weight: 35-45 parts of polyacrylamide, 15-25 parts of polymeric aluminium, 12-18 parts of expanded graphite, 15-20 parts of zeolite mineral, 20-30 parts of hydrolyzed tannin, 3-5 parts of organic acid, 5-10 parts of TiO2, and 3-5 parts of chitosan-graphene composite material. The oil-containing wastewater treatment agent disclosed by the invention has the advantages of being good in treatment effect, low in production cost, high in purity, free from toxicity, influence to operators and secondary pollution after treatment; the preparation method is simple and easy for popularization.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an oily wastewater treatment agent and a preparation method thereof. Background technique [0002] With the development of society, oil gradually invades water bodies to form oily wastewater; oily wastewater comes from a wide range of sources, mainly from industrial production and human life. The types of oily wastewater are complex and come from a wide range of sources. For example, oily wastewater mainly composed of light hydrocarbons, heavy hydrocarbons, fuel oil, tar, lubricating oil, and fat comes from petroleum exploration, petrochemical, steel, coking, and machinery industries. The oily wastewater mainly composed of animal and vegetable oils, waxes, phospholipids and soaps comes from light industries such as grain and oil processing, meat processing, food and cosmetics, catering industry and residential life. The amount of industrial oily wastewater is large, and...
