Problems solved by technology

[0004] The above-mentioned patents also have the following shortcomings: photocatalysis needs to solve the problem of light transmittance, because some suspended solids and darker chroma in printing and dyeing wastewater are not conducive to the transmission of light, which will affect the photocatalytic effect, but the above-mentioned The device does not bleach the wastewater first, and the chroma contained in the wastewater will reduce the photocatalytic effect

Abstract

The invention belongs to the technical field of wastewater treatment, in particular to a photocatalytic oxidation device for printing and dyeing wastewater treatment. Directed at the problem that wastewater chromaticity affects the catalytic effect, the invention puts forward the following scheme that: the device comprises a bottom plate, an ozone generator and a bleaching box are arranged on theouter wall of the top of the bottom plate, an air distribution pipe is arranged on the inner wall of the bleaching box, aeration discs distributed at equal intervals are arranged on the outer wall ofthe air distribution pipe, the inner wall of one side of the air distribution pipe and the output end of the ozone generator are provided with the same first guide pipe, and the air distribution pipeis of a V-shaped structure. The ozone method generator, the aeration discs, a first stirring rod, the air distribution pipe, an inclined rod, an elastic rope and a stirring frame are arranged; firstly, a dye can acquire a good decolorization effect through an ozone oxidation method, the air distribution pipe and the first stirring rod are both of a V-shaped structure, ozone and wastewater can be comprehensively and uniformly mixed by the first stirring rod at the first time after ozone is sprayed out of the aeration discs, and the decolorization effect of ozone can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a photocatalytic oxidation device for printing and dyeing wastewater treatment. Background technique [0002] Printing and dyeing wastewater is wastewater discharged from cotton, hemp, chemical fiber and their blended products, silk-based printing and dyeing, wool dyeing and finishing, and silk factories. The type of fiber and processing technology are different, and the water quantity and quality of printing and dyeing wastewater are also different. [0003] After retrieval, the Chinese patent authorization number is CN208814710U, which discloses a photocatalytic oxidation sewage treatment device, which includes a pipeline mixer and a photocatalytic oxidation treatment tank arranged in sequence, and the pipeline mixer is a pipeline type sewage processor. [0004] The above-mentioned patents also have the following shortcomings: photocatalysis needs to solve the pro...
