摘　　要：对脉冲电晕等离子体技术净化有机污染物二甲苯进行了实验研究,考察了脉冲峰值电压、脉冲频率、气体流量、气体入口质量浓度等因素对净化效率的影响。结果表明:二甲苯去除率随脉冲峰值电压、脉冲频率的增大而升高,随气体流量、气体进口质量浓度的增大而降低。该方法对低浓度、大流量的二甲苯废气能达到较好的去除效果,最高去除率可达87．4%。The article conducts experienmental study on cleaning organic pollutants with pulse corona plasma technology. The experiments were conducted on different parameters, such as pulse peak voltage, pulse frequency, gas flow rate, inlet concentration of toluene. The results indicated that the cleaning efficiency increased with peak voltage, pulse frequency increment and decreased with the increment of inlet concentration of xylene and gas flow rate. This method can gain a better result on treatment of waste gas of xylene with low concentration and big flow rate. The highest removal rate of xylene reaches at 87.4%.
