の再生装置。[Scope of Claim for Utility Model Registration] (1) Supplying organic solvent waste liquid preheated by a plurality of heat exchangers to a distillation column, flooding at least one shelf provided in the center of the distillation column, and storing the liquid at the bottom. Then, the stored liquid is heated with a heater provided at the bottom to bring its vapor into contact with the overflowing water, and the evaporated gas passes through a gas separation membrane to remove impurities and is condensed in a condenser to form recycled organic solvent. An apparatus for regenerating organic solvent waste liquid, characterized in that the organic solvent waste liquid is regenerated and distilled. (2) The apparatus for regenerating an organic solvent waste liquid according to claim 1, which is characterized in that the organic solvent waste liquid containing an acid is distilled in a distillation column after addition of an alkali.
