摘　　要：对高压脉冲放电等离子体技术降解水中有机污染物苯酚进行了实验研究 ,观察了脉冲成形电容、脉冲峰值电压、脉冲频率、放电电极直径、放电距离、苯酚的入口质量浓度等因素对苯酚降解率的影响 ;实验结果表明脉冲成形电容有一最佳值 ;降解率随脉冲峰值电压、脉冲频率增大而升高 ,随放电电极直径和放电距离的减小而增大 。This article is an experimental research about cleaning organic pollutant by high voltage pulsed discharge plasma.The factors that affect the rate of degradation are discussed,such as the pulse electric capacitor,pulse peak voltage,pulse freguency,the diameter of the discharge electrode,the distance between the electrodes and the inlet concentration.The experiment results show that there is a best capacitor value,the degradation efficiency increases with peak voltage and pulse frequency increment,with the diameter of the discharge electrode and the distance between the electrodes decrement and it increases with the inlet concentration increment.
