The chemical wastewater treatment agent comprises thefollowing raw materials in parts by mass: 25-38 parts of an inorganic-organic flocculant, 15-27 parts of an adsorbent, 10-18 parts of cured bayberry tannin, 10-18 parts of sulfuric acid modified pineleaves, 10-15 parts of a composite biochemical adsorbent, 8-12 parts of activated bentonite, 5-8 parts of fly ash, 8-8 parts of turf, 3-8 parts of modified zeolite, 3-8 parts of diatomite and 3-8 parts of modified kaolin.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a chemical wastewater treatment agent and a preparation method thereof. Background technique [0002] The chemical industry is a multi-industry and multi-variety industrial sector, including chemical mines, petrochemical industry, acid-base industry, chemical fertilizer industry, plastic industry, dye industry, detergent industry, etc. Chemical wastewater is produced from the production process of each chemical product Among them, a large amount of printing and dyeing wastewater that is difficult to treat is also produced in the printing and dyeing industry; printing and dyeing wastewater is 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, of which 80-90% becomes wastewat...
