Abstract

The invention discloses a sewage treatment agent special for printing and dyeing wastewater. The sewage treatment agent is prepared from, by weight, coal ash, wooden activated carbon, poly aluminium chloride, polyferric sulfate, polyacrylamide, ammonium persulfate, sodium carbonate, poly-ferric aluminum sulfate, aluminum sulfate, yttrium oxalate, manganese sulfate, sodium bentonite, zeolite, sepiolite, modified lignin sulfonate, alkylphenol ethoxylates, amino trimethylene phosphonic acid, menthone, thiourea, cationoid starch derivatives, sodium dodecyl benzene sulfonate, dimethyl diallyl ammonium chloride, octaphenyl polyoxyethyiene, glycerin monostearate, peroxiredoxin and microbial bacterial liquid. The microbial bacterial liquid is prepared from saccharomycetes, fusarium oxysporum, proteusbacillus vulgaris, neurospora and mycoplana. The invention further provides a preparation method of the sewage treatment agent. The prepared sewage treatment agent is good in treatment effect on the printing and dyeing wastewater, the preparation method is simple, and no secondary pollution exists.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a special sewage treatment agent for printing and dyeing wastewater and a preparation method thereof. Background technique [0002] Printing and dyeing wastewater is wastewater discharged from printing and dyeing factories that mainly process cotton, hemp, chemical fibers and their blended products. Printing and dyeing wastewater has a large amount of water, 100-200 tons of water is consumed per ton of textile printing and dyeing, and 80-90% of it becomes wastewater. Textile printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. It is one of the most difficult industrial wastewater to treat. Printing and dyeing wastewater is a major discharge of industrial wastewater. Statistics show that in 2008, the textile industry discharged 2.3 billion tons of wastewater,...
