Abstract (en)
Disclosed is a method for treating a photographic processing waste solution which comprises evaporating a photographic processing waste solution by heating and cooling a vapor generated by the heating by use of a cooling device to obtain a distilled solution, and a treatment device therefor which comprises a treatment tank for performing heating treatment of the photographic processing waste solution, a device for discharging the heated and concentrated solution of the photographic processing waste solution from the treatment tank, a receiving tank for the discharged solution, a device for performing cooling treatment of vapor generated by the heating treatment, a recovering tank for recovering a distilled solution generated by the cooling treatment, and a control device for controlling heating treatment according to the progesss of treatment of the waste solution.
