PROBLEM TO BE SOLVED: To provide a photographic waste solution treatment method by which COD (chemical oxygen demand) contribution substances and amonia nitrogen can effectively be reduced to levels satisfying the emission standard to a sewer in a photographic waste solution comprising COD contribution substances and ammonia nitrogen components in high concentrations. SOLUTION: In the treatment method for the photographic waste solution, the photographic waste solution is subjected to electrolytic oxidation treatment, and is thereafter subjected to ammonia nitrogen compound adsorption treatment. It is effective that catching is performed with zeolite as an adsorbent. COPYRIGHT: (C)2005,JPO&NCIPI
