Abstract

The invention discloses a printing and dyeing sewage treatment agent which is mainly prepared from the following components in parts by weight: 10 parts of sodium polyacrylate, 5-25 parts of starch, 30-50 parts of bentonite, 5-15 parts of ferric sulfate, 5-15 parts of alum, 0.5-1.5 parts of aluminum sulfate, 1-9 parts of activated carbon, 1-7 parts of basic aluminum oxide, 0.5-1.5 parts of ferrous sulfate, 0.2-0.8 part of nickel nitrate, 10-20 parts of chitosan and 0.02-0.08 part of polysorbate. Compared with the prior art, the printing and dyeing sewage treatment agent disclosed by the invention is simple in process and low in cost, can significantly improve the chroma removal rate, the turbidity removal rate and the COCcr removal rate of printing and dyeing sewage, and is excellent in performance.

Description

technical field [0001] The invention relates to a printing and dyeing sewage treatment agent, which belongs to the technical field of printing and dyeing sewage treatment. Background technique [0002] According to statistics, in 2003, among the various industrial industries in the country, the top five industries with the largest amount of wastewater discharge were papermaking, chemical manufacturing, electric power, ferrous metal smelting, and textile printing and dyeing. Among various industrial industries, the textile printing and dyeing industry The discharge of COD ranks fourth. It can be seen that the sewage discharge of the printing and dyeing industry needs to be treated urgently. The sewage discharged by the printing and dyeing factory mainly includes bleaching wastewater, printing, dyeing wastewater and desizing water, which is different from the wastewater discharged by other industries. of. At present, the treatment of printing and dyeing wastewater mainly incl...
