TREATING EQUIPMENT AND TREATMENT FOR TREATED WASTE LIQUID OF NONSILVER SALT PHOTOSENSITIVE MATERIAL

摘要

PURPOSE:To stabilize operation in a long time and to improve workability in an equipment and a method for heating the treated waste liquid of nonsilver salt photosensitive material in a heating and concentrating kiln and separating it into a liquid component and concentrate. CONSTITUTION:A treatment equipment for the treated waste liquid of nonsilver salt photosensitive material is equipped with a means for heating this treated waste liquid in the reduced pressure conditions to vaporize and concentrate it, a means for cooling and condensing the vapor generated thereby and a means for storing this condensate. A controlling means is added to the treatment equipment so that actuation is automatically performed in a time for starting operation of this treatment equipment and in a time for finishing operation thereof. Further a treating method is obtained so that the treatment equipment is used and operation is automated until a time for finishing operation of this treatment equipment from a time for starting operation thereof.
