| description | The invention provides a catalyst for treating wastewater as well as a preparation method and application thereof. The preparation method comprises the following steps: firstly, preparing active metal-loaded active carbon; then uniformly mixing the modified silica-alumina, organic fibers, a binder and an acid solution, then adding the active metal-loaded active carbon, forming, drying and roasting to obtain a catalyst precursor; and further treating with an organic solvent and a caustic soda solution, washing, drying and roasting to obtain the catalyst. The catalyst for treating wastewater has a stepped pore size distribution through pore channel structure, and is beneficial to diffusion and adsorption of organic matters in pore channels; the active metal components in the catalyst are intensively distributed on the active carbon, and the catalyst shows good activity and stability in the advanced oxidation treatment process of sewage containing organic matters.
