Abstract

The invention relates to the technical field of wastewater treatment, and particularly relates to a dyeing wastewater treatment agent and a preparation method thereof. The dyeing wastewater treatment agent comprises the following raw materials in parts by weight: 2-10 parts of ferrous sulfate, 20-30 parts of magnesium sulfate, 0.5-2 parts of polyacrylamide, 10-20 parts of iron nitrate, 1-5 parts of nickel nitrate, 40-60 parts of polyaluminum chloride, 10-20 parts of modified kieselguhr, 8-22 parts of meerschaum powder, 10-20 parts of crosslinked rectorite, 5-10 parts of chitosan-graphene composite material and 1-3 parts of graphene nano layer/MnO2 compound. The dyeing wastewater treatment agent provided by the invention has the advantages of convenient production method, low investment, quick effect taking and no secondary pollution.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a printing and dyeing sewage treatment agent and a preparation method thereof. Background technique [0002] Industrial wastewater refers to the wastewater, sewage and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products and products lost with water, as well as pollutants produced in the production process. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Therefore, for the protection of the environment, the treatment of industrial wastewater is more important than the treatment of urban sewage. [0003] The printing and dyeing industry consumes a lot of water, usually 100-200t of water is consumed per ton of textiles for...
