Abstract

The invention discloses an industrial wastewater treatment agent and a preparation method thereof, and relates to the technical field of water treatment; the industrial wastewater treatment agent comprises the following raw materials: 15-20 parts of polyferric sulfate, 10-15 parts of polyaluminum chloride, 50-70 parts of polyacrylamide, 3-6 parts of calcium oxide, 20-30 parts of composite particles, 5-10 parts of sodium tripolyphosphate, 5-8 parts of zinc salt, 2-3 parts of nano-silver dispersion liquid, 1-2 parts of essence and 10-15 parts of deionized water. The preparation method comprisesthe following steps: uniformly stirring polyferric sulfate, polyaluminum chloride, calcium oxide, composite particles and deionized water in a reactor at room temperature, then slowly heating the mixture to 50-60 DEG C, adding polyacrylamide, fully stirring the mixture to fully mix the raw materials, then slowly heatingthe mixture to 80-100 DEG C, adding sodium tripolyphosphate and zinc salt, fully stirring the mixture to obtain a mixed solution of polyferric sulfate, polyaluminum chloride, calcium oxide, composite particles and zinc salt; after the mixture is cooled to room temperature, adding the nano-silver dispresion liquid and the essence with complete stirring to obtain the product. According to the invention, the treatment efficiency of industrial wastewater is comprehensively improved, and the multifunctionality of the treatment agent is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an industrial wastewater treatment agent and a preparation method thereof. Background technique [0002] Over the years, the water environment has continued to deteriorate, and water pollution accidents caused by pollution have continued to occur, resulting in large economic losses and adverse social impacts. These adverse effects not only seriously threaten the sustainable development of society, but also threaten human beings. Survive. [0003] Water pollution is mainly caused by pollutants produced by human production and life, mainly including: industrial pollution, agricultural pollution and domestic pollution. With the rapid development of my country's industry, a large amount of industrial wastewater has been produced. Industrial wastewater has complex components and has the following characteristics: high organic content, high chemical oxygen demand, poor biodeg...
