A PCB (polychlorinated biphenyls) detoxification plant is composed of "pre-treatment process "and" decomposition process". Authors proposed the UV (ultraviolet rays)/Catalyst method by which the reaction is performed at a low temperature and an atmospheric pressure as a decomposition process and the thermal recycling using dechlorinated oil is proposed. The basic experiment on the decomposition characteristic of the UV/Catalyst method was carried out concerning PCBs contaminated by unexpected impurities such as solvent for washing and organic chemicals like pyroligneous acid. Even if there is contamination, PCBs were decomposed experimentally below the level which is less than PCB standard by UV/Catalyst method. This study showed the validity of the application of UV/Catalyst method for PCB detoxification plants.
