Abstract

The invention provides a high-efficiency papermaking wastewater treatment agent, which is prepared from the following components in parts by weight: 10 to 20 parts of phthalamide-based ferrocene polyphenyl ether, 10 to 15 parts of mesoporous Ti-Al-O, and 30 to 40 parts of modified polyetheramine, wherein the phthalamide-based ferrocene polyphenyl ether is prepared by a chemical reaction of 1,1'-ferrocene dibromide, 4-hydroxybenzeneboronic acid, and 4,5-dichlorophthalamide. The invention also discloses a preparation method of the high-efficiency papermaking wastewater treatment agent. The high-efficiency papermaking wastewater treatment agent prepared by the invention has the advantages of more stable performance, better wastewater treatment effect, higher efficiency, lower cost, less usage, less environmental pollution, and antibacterial, anti-fouling and anti-corrosive properties at the same time.

Description

technical field [0001] The invention relates to the technical field of papermaking wastewater treatment, in particular to a high-efficiency treatment agent for papermaking wastewater and a preparation method thereof. Background technique [0002] The paper industry is one of the industries with large water consumption and heavy pollution. The wastewater discharged by the paper industry during the production process contains many types of organic pollutants, which are difficult to deal with, seriously endangering the living environment of aquatic organisms, plants and humans, and destroying water resources. use value. Therefore, it has significant economic and social value to treat and recycle the wastewater generated at each stage of the papermaking process. [0003] Papermaking wastewater is a kind of industrial wastewater that is difficult to treat. At present, many papermaking industries at home and abroad use chemical oxidation method + flocculation sedimentation method...
