Abstract

The invention discloses a sewage treatment agent for printing and dyeing wastewater. The sewage treatment agent is prepared from the following raw materials in parts by weight: 8-11 parts of aluminum sulfate, 10-13 parts of ferric phosphate, 3-6 parts of seaweed mud, 11-15 parts of sea-foam stone powder, 2-5 parts of nano-zinc oxide, 1-3 parts of active calcium silicate, 15-19 parts of trimethylene di(octadecyl dimethyl) ammonium-bentonite, 1-2 parts of ethylene glycol tetraacetic acid, 2-5 parts of a chitosan-graphene composite material, 24-27 parts of polyaluminum ferric chloride and 18-22 parts of polyacrylamide. The invention further discloses a preparation method of the sewage treatment agent for printing and dyeing wastewater. The sewage treatment agent disclosed by the invention is capable of effectively removing pollutants in printing and dyeing wastewater, good in treatment effect, low in treatment cost, free from toxicity and free from secondary pollution.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment agent for printing and dyeing wastewater and its preparation method and application. Background technique [0002] The printing and dyeing industry consumes a lot of water, usually 100-200t of water is consumed per ton of textiles for printing and dyeing, 80-90% of which is discharged as printing and dyeing wastewater. Common treatment methods include recycling and harmless treatment. Recycling: (1) Wastewater can be recycled according to the characteristics of water quality, such as the diversion of bleaching and scouring wastewater and dyeing and printing wastewater, and the former can be washed by convection. One water can be used for multiple purposes, reducing emissions; (2) lye recovery, usually by evaporation, such as a large amount of lye, can be recovered by three-effect evaporation; if the amount of lye is small, it can be recovered by thin ...
