METHOD AND APPARATUS FOR TREATING PHOTOGRAPHIC PROCESSING WASTES

摘要

PURPOSE:To enable distilled liquid to be obtained by heating waste water and cooling the vapor produced by evaporating it. CONSTITUTION:The photographic processing waste water overflowing from the photographic processing bath of an automatic developing machine is stored in a stock tank, this volume and/or the volume of the photographic processing waste water in the processing means are detected, and the waste water is fed from the stock tank to a treating means in accordance with the obtained information. The waste water is evaporated with a heating means to concentrate the waste water or to dry it up, the vapor is condensed with a cooler, and to reuse the distilled water for the photographic processing process.
