Abstract

The invention discloses a method and equipment for recycling textile printing and dyeing wastewater. The equipment includes an initial adsorption mechanism and an electrochemical catalysis mechanism. There is a cylinder cover, a reducer is installed in the middle of the cylinder cover, the output end of the reducer is connected with a stirring shaft extending into the inside of the mixing cylinder, and stirring blades for stirring the coke layer are distributed on the stirring shaft; the electrochemical catalytic mechanism includes The waste water treatment tank body is provided with a water inlet on the left end side wall of the waste water treatment tank body, and a water outlet is arranged on the right end side wall of the waste water treatment tank body. The inside of the waste water treatment tank body is located between the water inlet and the water outlet. An anode electrode plate and a cathode electrode plate are assembled, the process layout of the invention is reasonable, the decolorization effect on the printing and dyeing wastewater is good, the suspended organic matter in the wastewater can be effectively removed, and the decomposition and treatment efficiency of the macromolecular organic matter is high.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing wastewater treatment, in particular to a recycling method and equipment for textile printing and dyeing wastewater. Background technique [0002] With the development of the economy, the problem of water pollution has become more serious, and dye wastewater is one of the important sources of water pollution. In 2015, China's dye production reached 1.15 million tons, ranking first in the world. A large amount of water resources are consumed in the process of producing dyes, and about 10-20% of dyes are released into water bodies during production and use. Dye wastewater has the characteristics of large changes in quality and quantity, high concentration of organic matter, large chroma, and strong alkalinity, and is difficult to treat. Therefore, it is of great significance to study the treatment of dye wastewater. At present, the main methods used to treat printing and dyeing wastewa...
