Abstract

The invention belongs to the technical field of high-concentration dye wastewater, and particularly relates to a segmented treatment method of high-concentration high-chromaticity dye wastewater. In the invention, electrochemical oxidation technology is optimally combined with photocatalytic oxidation technology to become a new electrochemical pre-oxidation-photoelectric collaborative oxidation-photocatalytic oxidation three-segment sewage treatment process, and an Sb*doped SnO2 / TiO2-NTs / Ti photoelectronic integrated electrode with excellent photoelectric catalytic properties concurrently is selected as anode material for degradation treatment. The process achieves prospective high-efficient treatment effect, saves energy consumption to the maximum extent, embodies the advantage of savingenergy, and provides a brand-new method for the degradation of the high-concentration high-chromaticity dye wastewater, thus having broad application prospect and development potential.

Description

technical field

[0001] The invention belongs to the technical field of high-concentration dye wastewater, and in particular relates to a segmented treatment method for high-concentration and high-chroma dye wastewater. Background technique

[0002] With the increasing variety and quantity of dyes, dye wastewater has become one of the key pollution sources of the water environment. Dye wastewater has the characteristics of high concentration of organic matter, high chroma, high content of inorganic salts, complex components, poor biodegradability, and difficulty in decolorization. Teratogenic, mutagenic) organic matter has always been a difficult point in industrial sewage treatment, and it is also a major problem that needs to be solved urgently in the field of water pollution control at home and abroad.

[0003] Advanced oxidation technology is a popular research technology that is considered to have good development prospects, mainly including wet catalytic oxidation, pho...
