采用大气压介质阻挡放电对含苯胺的废水进行了处理,研究各种因素对苯胺废水处理效果的影响,对处理过程中溶液的总有机碳（TOC）、pH和电导率的变化进行了测定,探讨放电特性和机制.结果表明：苯胺降解率随反应时间的延长而增加;初始浓度升高,苯胺去除率降低,去除量增加;电导率增加、溶液中添加Na2 SO4和NaNO3时均会降低苯胺去除率;投加H202对DBD起协同作用,电极距液面4 mm,放电功率235 W,反应10 min时去除率最高由35.76％增加至89.86％.

英文摘要：

A dielectric barrier discharge（DBD） reactor was designed for treatment of aniline wastewater. Discharge characteristics were measured by voltage and current waveforms,light-emission pictures and op- tical emission spectroscopy. The effects of various parameters like aniline concentration, wastewater con- ductivity, addition of Na2SQ, NaNO3 and H202, change in total organic carbon （ TOC ）, pH and conduc- tivity were investigated for organic compound degradation. Results showed that the abatement of aniline increased with the treatment time. Under the same conditions,the degradation rate decreased with the in- creasing of the wastewater conductivity and addition of Na2 SO4 and NaNO3. Adding a certain dosage of hydrogen peroxide to the wastewater could accelerate the degradation rate of the aniline. Removal rate in- creased from 35.76% to 89. 86% after 10 rain discharge at 235 W of discharge power and 4 mm of dis- tance.
