中文摘要：

将四氯乙烯，间二甲苯气态混合物同时引入无声放电反应器，加工频正弦交流高压对混合污染物进行放电分解实验．结果发现：与单一组分污染物的降解特性相比，混合气体中四氯乙烯的降解率变化较大，最大降解率由单独处理时的76％下降到27％，而间二甲苯的降解率基本保持不变，最大降解率可达90％左右；相同条件下，不锈钢棒高压电极对污染物的降解效果要略好于螺纹钢棒电极；3种电极间距对混合气体的降解效果依次为5mm〉7．5mm〉10mm．

英文摘要：

AC high voltage power is introduce into dielectric barrier discharge reactor to investigate the decomposition character of tetrachloroethylene and 1,3-xylene mixture. The results indicate that compared with the decomposition characters of single-composition, the highest decomposition rate of tetrachloroethylene changes from 76 % to 27 % and the rate of 1,3-xylene is maintaining about 90 % in the processing of mixture; Better results are attained with stainless steel stick as the high voltage electrodes than screw thread steel stick; Three electrode gaps of the reactor show different decomposition ability as： 5 mm〉7.5 mm〉 10 mm.
