AI Technical Summary

Problems solved by technology

[0003] my country's printing and dyeing industry is developing rapidly, the discharge of printing and dyeing wastewater is large, and the composition is complex and difficult to treat. However, the efficiency of the existing adsorbents for the treatment of printing and dyeing wastewater is still low, resulting in the discharge of printing and dyeing wastewater that cannot meet the standard after treatment.

Abstract

The invention discloses a printing and dyeing wastewater purifying agent. The printing and dyeing wastewater purifying agent is prepared from the following raw materials in parts by mass: 20 to 25 parts of activated carbon, 10 to 12 parts of fly ash, 1 to 2 parts of white alum, 10 to 15 parts of macroporous anion exchange resin and 2 to 8 parts of polyamide resin. The macroporous anion exchange resin is D301 macroporous anion exchange resin or D201 macroporous anion exchange resin. The printing and dyeing wastewater purifying agent disclosed by the invention is high in adsorbability, a removalratio of COCcr of textile printing and dyeing wastewater is up to 80 percent, a removal ratio of turbidity is up to 901 percent, and a removal ratio of the chromaticity is up to 892 percent.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to a printing and dyeing wastewater purifier. Background technique [0002] Water is an important natural resource for the survival and development of human society. With the rapid development of industry, water pollution is constantly escalating, and the wastewater produced by printing and dyeing is an important source of water pollution. At present, the treatment of printing and dyeing wastewater mainly includes adsorption method, coagulation method, oxidation method, membrane separation method and biochemical method, among which adsorption method is the most widely used treatment method. The adsorption method mainly uses porous adsorbent to adsorb the pollutants in the wastewater on its surface to purify the water quality. [0003] my country's printing and dyeing industry is developing rapidly, the discharge of printing and dyeing wastewater is large, and the com...
