SOLUTION: The formalin waste liquid is circulated to an active oxygen generating means 8 to be detoxified. Active oxygen is generated by applying an electric current to an electrode made of a conductive member to which polyaniline adheres. A storage tank 1 and a treatment tank 4 are independently installed. COPYRIGHT: (C)2007,JPO&INPIT
