Description

technical field [0001] The invention relates to the technical field of catalysts, in particular to a special catalyst for high-concentration organic wastewater treatment and a wastewater treatment method. Background technique [0002] Catalysts currently used in sewage treatment include the following: [0003] One is photocatalyst. It is a special photosensitized oxidation that uses n-type semiconductors as sensitizers. The most widely used are sulfur compound semiconductors (mainly TiO2) and polymetallic acid (POM). The application of photocatalyst in sewage treatment can remove various organic substances, as well as heavy metal ions and cyanide ions, without secondary pollution, and the treatment is relatively thorough. [0004] The second is the electrocatalyst. Refers to the use of suitable anode materials, such as Pt, Ti / PbO 2 , Sb / SnO 2 And other anode materials can effectively reduce organic pollutants in organic wastewater. Electrocatalytic treatment of sewage ...
