Abstract

The invention relates to a device for treating sewage and wastewater through photocatalytic degradation. The device is integrally divided into a basic structure unit, a water inlet and drainage system, a sunlight unit, a stirring system, an aeration system, a self-control unit and an auxiliary illumination system. The device is suitable for large-scale photocatalytic treatment of sewage and wastewater.

Description

[0001] Technical field [0002] The invention relates to a device for photocatalytic degradation and treatment of sewage and wastewater, and is especially suitable for the treatment of low-flow and high-concentration sewage and wastewater in environmental protection work. Background technique [0003] At present, with the continuous and rapid development of the industrial industry, various wastewater and sewage that are difficult to treat have been brought, such as high salt, high chemical oxygen demand (COD), high sulfur, high nitrogen, high chlorine, high complexes, Wastewater with high heavy metal content. Traditional biological, physical, and chemical water treatment processes are difficult to achieve a satisfactory COD degradation effect in the face of this type of sewage. [0004] Photocatalysis technology has the following advantages in treating such sewage and wastewater: photocatalysis is green and environmentally friendly, and the degradation products are small mole...
