Abstract
Recently, advanced water treatment technology has been studied for effective utilization of O and OH radicals which have stronger oxidation potential than ozone. They can decompose persistent substance, such as dioxin. In this study, the characteristics of multiple bubble jet il! which streamer is generated by DC pulsed discharge, are experimentally clarified through decomposition of acetic acid solution as a persistent substance. The concentration of acetic acid is 23-27 mgtoc/l in 550 ml solution, feeding gas is argon and operation time is 60 min. The acetic acid solution is successfully decomposed by OH radical in present multiple bubble jet system. The optimization frequency is found to be 800 Hz for acetic acid decomposition.
