The invention creatively provides a method for removing hydrogen peroxide from an organic solvent-water solution. The method comprises the following steps: mixing a hydrogen peroxide-containing mixed solvent with an additive and introducing the obtained mixture to a tower type deoxidation reactor, or respectively individually introducing the hydrogen peroxide-containing mixed solvent and the additive to the tower type deoxidation reactor, blowing inert gas to the bottom of the tower, condensing a material from the top of the tower, carrying out gas phase evacuation, and returning the obtained liquid phase to the deoxidation reactor; and allowing a liquid phase from the bottom of the tower to a rectifying tower, and carrying out solvent separation. The method makes the content of hydrogen peroxide in the organic solvent-water solution be reduced to 100ppm or below; and compared with existing catalytic hydrogenation methods, the method provided by the invention has the advantages of simplicity, effectiveness, low cost, high economy, avoiding of use of explosive gas hydrogen, and improvement of the safety.
