Harmful organic air pollution matter influences ecology system. DIOXINS are main matters. The Ministry of Environment says the hazardous waste should be burned at 1, 200°C or more. This content means a benzen circle chlorine will be cut from the benzen circle. But it cann’t break benzen circles. Benzen circles can recombine chlorines. Therefore benzen circles should be broken. This research tried to destroy benzen circles by arc. In the first experiment biphenyl was treated by arc. In the second experiment a benzen gas and a chlorobenzen gas were treated by arc. The first one broke the biphenyl by 99.9965%. In the second the benzen gas was treated by 45.92% and the chlorobenzen gas by 89.95%.
