The invention belongs to the technical field of radioactive waste treatment, and relates to an efficient adsorption treatment method for a radioactive waste resin Fenton oxidation waste liquid. The method comprises: (1) filtering a radioactive waste resin Fenton oxidation waste liquid to remove the residue and the insoluble matter, and adsorbing with a molecular sieve; and (2) measuring the nuclide radioactivity concentration of the waste liquid adsorbed by the molecular sieve, directly discharging the waste liquid if the measured value is lower than a set value, and making the waste liquid return to the molecular sieve and be adsorbed if the measured value is higher than or equal to the set value. According to the present invention, with the method, the deep purification treatment of thekey feature nuclides Co-60, Cs-137 and Sr-90 can be achieved while the characteristics of the original waste liquid are substantially unchanged, and the treated waste liquid can meet the direct discharge requirement (the tota
