Abstract

The invention discloses a sewage treating agent, which is prepared from the following ingredients 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 white alum, 0.5-1.5 parts of aluminum sulfate, 1-9 parts of activated carbon, 1-7 parts of basic aluminium 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 parts of polysorbate. Compared with the prior art, the sewage treating agent has the advantages of simple technology and low cost, the chroma removing rate, the turbidity removal rate and the COCrr removal rate of printing and dyeing sewage can be obviously improved, and performance is excellent.

Description

technical field [0001] The invention relates to a sewage treatment agent, belonging 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 includes adsorption method, ...
