Catalytic wet oxidation catalyst for wastewater and preparation method thereof

The invention relates to a catalytic wet oxidation catalyst for wastewater and a preparation method thereof, which mainly solve the problems of biological inhibition, low COD removing rate and complex process during treatment of sulfur-containing wastewater or problems that other organic pollutants in the wastewater and secondary pollution cannot be handled during treatment of cyanide-containing wastewater. The catalytic wet oxidation catalyst for wastewater comprises the following components in parts by weight: 90-99.9 parts of at least one oxide carrier selected from TiO2, Al2O3, SiO2 or ZrO2, 0.1-10 parts of at least one metal or oxide selected from Pt, Pd, Ru, Ir or Rh carried thereon and 0.01-5 parts of at least one oxide selected from Bi, Ba, Mg, B, V, Mo or rare earth. By the technical scheme using the catalytic wet oxidation catalyst for wastewater, the invention solves the problem better and can be used in industrial treatment of industrial organic wastewater.
