METHOD AND APPARATUF FOR TREATING WATER CONTAINING ORGANIC COMPOUND INCLUDING NONIONIC SURFACTANT

摘要

PROBLEM TO BE SOLVED: To provide a new waste water treatment method and apparatus for completely decomposing water containing organic compounds including a nonionic surfactant to inorganics such as carbon dioxide and water and removing it efficiently in electrolytic treatment utilizing diamond for an electrode.;SOLUTION: The water containing the organic compounds including the nonionic surfactant is electrolytically treated at a temperature not lower than the clouding point of the nonionic surfactant by an electrolytic device using conductive diamond for an anode 1 and a cathode 2. In this method, the surfactant and the other organic compound are effectively decomposed and detoxicated at the time of the electrolytic treatment. Also, the electrode is excellent in corrosion resistance against common acid and alkali, only a target organic substance is efficiently decomposed by oxidization in a wide pH range from an acid condition to an alkali condition, and a stable treatment effect is sustained over a long period of time. Then, the water containing the organic compounds including the nonionic surfactant is electrochemically decomposed by the oxidization and removed by extremely high current efficiency and energy efficiency and an economical merit is large.;COPYRIGHT: (C)2004,JPO&NCIPI
