Aging aluminum removal agent recycling process

The invention belongs to the technical field of industrial hazardous waste treatment, and particularly relates to an aging aluminum removal agent recycling process which comprises the following steps: (1) adding water into an aging aluminum removal agent, and stirring to obtain a mixed solution; (2) adding oxalic acid into the mixed solution, and stirring to obtain turbid liquid; (3) removing solid materials from the turbid liquid to obtain clear liquid; (4) standing the clear liquid, layering, and taking the upper layer to obtain a crude organic phase; (5) adjusting the pH value of the crude organic phase with a NaOH solution, then adding water for dilution, stirring, standing for layering, and taking the upper layer to obtain a refined organic phase; and (6) adding hydrochloric acid and water into the refined organic phase for washing, standing for layering, taking supernatant liquid, and finally obtaining an upper organic phase, namely the regenerated aluminum removal agent.
