Abstract
An apparatus for treating a photographic process waste liquor in which the photographic process waste liquor stored in an evaporating device is heated and concentrated by evaporation with use of a heating device provided in the evaporating device, in that the evaporating device is provided with a precipitate separating device capable of separating a precipitate generated in a concentrated liquid to be formed through concentration by evaporation; a circulation system to feed again the concentrated liquid to the evaporating device through the precipitate separating device; and a discharging device for discharging the precipitate separated at the precipitate separating device. By use of the apparatus for treating photographic process waste liquor, thermal decomposition of the precipitate generated by concentration by evaporation of the photographic process waste liquor and generation of bad odor can be inhibited.
