摘　　要：为了解决液相放电电极腐蚀,引起放电状态不稳定的难题,本文采用高压放电针状电极位于液面上方的气相中,低压接地电极位于液相中的针-板电极脉冲放电反应器,对溶液中难降解有机物进行降解.主要研究通入气体种类及气量、苯酚浓度、输入能量等因素对苯酚降解率的影响,目的是了解影响气相脉冲放电对水中有机物降解的影响条件,为脉冲放电水处理技术应用提供参考.Discharges in liquid atmosphere the discharge electrodes corrupt quickly cause the state unstable. For solving this problem, this paper introduces a gas pulsed discharge needle-plant reactor for decomposition organic contaminant in water, namely the discharge needle electrode locates above the liquid in gas atmosphere, and the ground electrode locates in liquid atmosphere. The effect of gas category and bubbling rate, concentration of phenol, discharge energy on the phenol decomposition efficiency is reviewed in the research. The motive is to know the factors of gas pulsed discharge decomposition organic contaminant for industrialization of pulse discharge for treating organic contaminant offer reference.
