Abstract

The invention relates to an industrial wastewater treatment agent and a preparation method thereof. The industrial wastewater treatment agent is prepared from the following components in parts by weight: 8-15 parts of inorganic filler, 5-10 parts of inorganic flocculant, 10-15 parts of modified graphene, 20-30 parts of modified natural polymer material and 30-40 parts of water. According to the preparation method, an amphiphilic random copolymer chain is formed on the surface of starch, and forms a bridging effect with particles in water, so that the flocculation capacity is enhanced; functional groups such as amido bonds and sulfo groups also exist in the structure of the copolymer, so that scaling of inorganic matters can be effectively controlled in a large range, and when the copolymeris compounded with other components in the treatment agent of the invention to be used, good scale inhibition performance can be generated. A polyacrylamide / graphene oxide hydrogel has adsorption andflocculation capabilities, can be used as a carrier stabilizer for loading inorganic fillers and inorganic flocculants, exerts adsorption and coagulation / flocculation effects of the fillers and the flocculants in a water body to the greatest extent, and enhances the adhesion with metal ions in the water body.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to an industrial wastewater treatment agent and a preparation method thereof. Background technique [0002] Physical method, chemical method, physicochemical method and biological method are common processes in water treatment technology at present. Among them, the physical chemical method is a way of comprehensive physical and chemical methods for water treatment. It learns from each other's strengths and complements its weaknesses. It has both physical adsorption precipitation and chemical redox, and combines the advantages of the two phases. Water treatment agent is an important class of fine chemical products, which play an important role in the purification and treatment of industrial sewage and domestic wastewater. Water treatment agents are divided into coagulation / flocculation agents, adsorbents, bactericides, scale inhibitors, corrosion inhibitors, etc. accor...
