This invention relates to a process by which waste water containing ammonia or chemically oxidizable substances (hereinafter referred to as "COD components"), suspended solids, etc. in addition to ammonia is subjected to wet oxidation in the presence of a catalyst to convert these pollutants to nitrogen, carbon dioxide, water and the like and to thereby render the waste water harmless.

According to this invention, the ammonia contained in the waste water includes ammonium compounds which liberate ammonium ions when dissociated in water. The COD components include phenol, cyanides, thiocyanates, oils, thiosulfuric acid, sulfurous acid, sulfides, nitrous acid, etc.
