Abstract

The invention provides an organic treating agent for papermaking wastewater. The organic treating agent is prepared from the following components in parts by weight: 40-50 parts of 2,4,6-trioxo-1,3,5-triazine-1,3,5(2H,4H,6H)-tripropionic acid modified hyperbranched polyethyleneimine, 10-20 parts of furan-2-methyl-(3,4,5-trimethoxy benzyl)-amine modified polyphenyl ether and 10-15 parts of modifiedTi-O-F-N, wherein furan-2-methyl-(3,4,5-trimethoxy benzyl)-amine modified polyphenyl ether is prepared by carrying out chemical reaction on benzophenone-4,4'-dicarboxylic acid, 2,7-dibromopyrene andfuran-2-methyl-(3,4,5-trimethoxyl benzyl)-amine. The invention also discloses a preparation method for the organic treating agent for the papermaking wastewater. The organic treating agent for the papermaking wastewater prepared through the preparation method has the advantages of being more stable in performances, better in wastewater treatment effect, higher in efficiency, lower in cost, smallerin usage amount and less in environmental pollution.

Description

technical field [0001] The invention relates to the technical field of papermaking wastewater treatment, in particular to a papermaking wastewater composite treatment agent and a preparation method thereof. Background technique [0002] The paper industry discharges a large amount of wastewater during the production process, which seriously endangers the living environment of aquatic organisms, plants and human beings, and destroys the utilization value of water resources. The so-called papermaking wastewater mainly refers to the middle water, which contains lignin, hemicellulose, sugars, residual alkali, inorganic salts, volatile acids, organic chlorides, etc., with large discharge, high COD, and pH variation range Large, high chroma, mercaptan-like odor, poor biodegradability, etc., are difficult to treat industrial wastewater. Treating papermaking wastewater is an effective measure to effectively control the deterioration of the water environment brought about by the pap...
