This application discloses a method for catalytic wet oxidation treatment of sodium thiosulfate. The method includes: contacting a raw material containing sodium thiosulfate with a catalyst and an oxidant to undergo an oxidation reaction to obtain sodium sulfate; wherein the catalyst includes a support and an active component; the support is activated carbon; the active component includes a transition metal active element; the transition metal active element is selected from one to three of Mn, Fe, Co, Ni, and Cu. This method can achieve oxidation of more than 60% of 10000 mg / L thiosulfate, and the catalyst activity can be restored by water washing and regeneration after a decrease. The catalyst morphology remains good after 30 days of continuous operation.
