The invention relates to the technical field of organic matter degradation, and concretely discloses a method for removing humic acid from uranium mine alkaline leachate. The method comprises the following steps: 1, preparing a catalyst; and 2, removing humic acid. The silica gel supported tetravalent vanadium ion type catalyst is adopted to catalyze ozonization degradation of the humic acid in the uranium mine alkaline leachate in the method, the catalyst is suitable for being used in an alkaline system, coordinates ozone degradation of the humic acid in the alkaline leachate, and improves the degradation efficiency; and the removal rate of the humic acid from uranium mine alkaline leachate by using the removal method, and reaches 65-80%.
