摘要:
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Na2SO4和NaNO3时均会降低苯胺去除率; 投加H2O2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%。
Abstract:
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 optical emission spectroscopy. The effects of various parameters like aniline concentration,wastewater conductivity,addition of Na2SO4,NaNO3 and H2O2,change in total organic carbon(TOC),pH and conductivity 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 increasing of the wastewater conductivity and addition of Na2SO4 and NaNO3. Adding a certain dosage of hydrogen peroxide to the wastewater could accelerate the degradation rate of the aniline. Removal rate increased from 35.76% to 89.86% after 10 min discharge at 235 W of discharge power and 4 mm of distance.
