Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a device for treating wastewater by photocatalytic oxidation. Background technique [0002] Photocatalytic oxidation is a water treatment technology, which uses semiconductors (usually TiO2) as catalysts to oxidize and decompose organic and inorganic pollutants in wastewater by photoexcitation to cause redox reactions. The principle of photocatalytic reaction can be explained by the energy band theory of semiconductors. Holes can interact with oH or H:O adsorbed on the surface of catalyst particles to generate oH, and oH is generally considered to be the main component in the photocatalytic reaction system. active oxide species. Photocatalysis has a wide range of applications, no secondary pollution, low energy consumption, and low cost. It has photolyzed organic pollutants such as methyl orange, reactive red, acid purple, and acid bright yellow, as well as Cr: o2-,...
