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 chemical treatment agents for 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 high-efficiency printing and dyeing wastewater treatment agent, whose raw material components include: 10-15 parts of alum, 30-40 parts of polyamide resin, 15-20 parts of polypropylene fiber, 18-22 parts of sodium hexametaphosphate, silicon Sodium acid 12-15 parts and fly ash 15-20 parts, described parts are mass parts. The high-efficiency printing and dyeing wastewater treatment agent of the present invention has high-efficiency purification ability, and can make the COCcr removal rate of textile printing and dyeing wastewater as high as 90%, the removal rate of turbidity as high as 95%, and the removal rate of chroma as high as 95%.

Description

technical field [0001] The invention relates to a high-efficiency printing and dyeing wastewater treatment agent and a preparation method thereof, belonging to the field of sewage purification. 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 physical methods, biological methods and chemical methods, among which chemical methods are widely used. [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 chemical treatment agents for printing and dyeing wastewater is still low, resulting in the...
