Abstract

The invention discloses a printing and dyeing wastewater treatment agent. The treatment agent is prepared through the steps that bentonite, starch and coal dust are evenly mixed, water is added, pulping is conducted, and the obtained pulp is extruded into particles with the diameter being 1 mm; the particles are put into the environment at the temperature ranging from 600 DEG C to 800 DEG C and burned for 7 hours; the prepared bentonite particles are added into a acrylamide aqueous solution to be stirred for 2 hours at a high speed at the temperature being 40 DEG C, ammonium persulfate is added into the mixture to be heated to be at 45 DEG C, a polymerization reaction is excited, when the temperature rises to 85 DEG C to 95 DEG C and falls to 60 DEG C, cross-linking agents are added into the mixture, the temperature rises to 70 DEG C, and reaction is conducted for 30 minutes; the mixture is transferred to the environment at the temperature being 105 DEG C, standing and drying are conducted, and the printing and dyeing wastewater treatment agent is obtained. By means of the printing and dyeing wastewater treatment agent, organic pollutants and inorganic pollutants in the printing and dyeing wastewater can be absorbed efficiently, and the agent can be used for physiochemical treatment of the printing and dyeing wastewater in the textile factories effectively.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and environmental protection, and relates to a sewage treatment agent, in particular to a treatment agent for physical and chemical treatment of wastewater in the printing and dyeing section of textile mills. Background technique [0002] Although dyes do not have strong acute toxic effects like pesticides, people have found mutagenic and carcinogenic species in azo dyes, anthraquinone dyes, and triphenylmethane dyes, and the degradation products of dyes are mostly linked. Some carcinogenic aromatic compounds such as aniline. As a class of organic compounds with stable structure, dyes have the characteristics of anti-acid, anti-alkali, anti-light, anti-microbial, etc., and have a long residence period in the environment. Very low concentrations of dyes in water will also affect the quality of receiving water. In normal function, it is also toxic to aquatic microorganisms and fish, reduc...
