Activated water, containing ozone and hydrogen peroxide, was sprayed into the exhaust gas of a small incinerator, to investigate the decomposition rate of the dioxins as well as the chlorobenzene and chlorophenol, which are both precursors. As a result, we found that there is a positive correlation between the dioxins and precursors at an atmospheric temperature of 400℃. An especially strong correlation was found in the low0chlorinated phenol. We found that the dioxin decomposition rate can be predicted according to the decomposition rate of the precursors. Furthermore, the decomposition rate for dioxins was low when the atmospheric temperature was increased, and in turn increased for precursors, showing that the decomposition mechanism is different for dioxins and precursors.
