The invention discloses a method for deeply purifying and recovering hyperhaline fluoric-U radioactive waste solution. The method comprises three sequent treatment phases including pretreatment, enrichment and separation of U-F and recovery of U, and can be further finely divided into 7 treatment units, including lower temperature reduction separation, chemical sedimentation, film filtering, step-grade organism enrichment-film filtering separation or step ion exchange, deposit fluorine removal solid-liquid separation, microwave tower treatment and resource recovery of U; under the condition that the salinity of waste solution to be treated is 0.1-10%, the initial U concentration is 0.1-1000mg/L, and the fluorine concentration is 0.01-15g/L, after treatment, the concentration of U is not larger than 0.05mg/L, the concentration of the fluorine is not higher than 10mg/L, and the recovery rate of U is larger than 90%. The method for deeply purifying and recovering hyperhaline fluoric-U radioactive waste solution is suitable for treating hyperhaline fluoric-U radioactive waste solution and the resource recovery of radioactive U.
