Abstract

A low-cost treating agent for printing and dyeing waste water is disclosed. The treating agent includes, by weight, 20-25 parts of polyacrylamide, 45-50 parts of fly ash, 12-18 parts of chitosan, 30-35 parts of straw powder, 25-30 parts of saw powder, 8-12 parts of sodium acetate, 12-16 parts of activated maifan stone, 15-19 parts of polymeric aluminum ferric sulfate, 3-6 parts of magnesium sulfate, 21-24 parts of a cation type starch derivative, 2-5 parts of glycerol monostearate, 6-10 parts of fluorite and 3-7 parts of sodium lignosulfonate. The invention also discloses a preparing method of the treating agent. The treating agent has efficient cleaning capability, can effectively reduce the COD, BOD, SS, ammonia nitrogen and chroma of sanitary sewage, has good treating effects, is convenient to use, and greatly reduces difficulty for treating the printing and dyeing waste water.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a low-cost printing and dyeing wastewater treatment agent and a preparation method thereof. Background technique [0002] With the continuous development of industry, the use of water resources has also increased, but there is less than 1% of fresh water on the earth and only about 0.007% of which can be directly used by humans. Therefore, saving water resources and reusing water Resources become the focus of attention. In the reuse of water resources, sewage treatment is the top priority. [0003] 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 wastewat...
