The invention relates to the technical field of industrial wastewater treatment, and particularly discloses chemical polishing waste liquid multi-stage extraction cyclic regeneration treatment equipment and a chemical polishing waste liquid multi-stage extraction cyclic regeneration treatment process. Chemical polishing waste liquid is filtered by a filter, then the filtered chemical polishing liquid enters a liquid storage barrel, and the chemical polishing liquid in the liquid storage barrel enters a primary extraction unit; and a load phase extracted in the primary extraction unit directly enters the cleaning unit. By arranging the outer barrel, the evaporation and concentration unit and the solution regeneration barrel, when the chemical polishing liquid is treated by the device, the chemical polishing liquid is efficiently extracted by the device through synchronous extraction of the primary extraction unit and the secondary extraction unit; meanwhile, the flocculating agent can be prepared by processing
