摘　　要：气液相等离子体放电技术在有机废水处理方面具备了特定的优势。为此,提出了一种双水电极气液相低温等离子体水处理反应器结构,对其放电机理及特性进行了分析。并在此基础上设计了一台输出电压峰值4.8kV、输出电流峰值100 mA的高压电源样机,利用双水电极放电反应器对苯酚溶液进行处理。在一定的实验条件下,苯酚溶液的化学需氧量(COD)去除率达到65%。实验结果表明:双水电极等离子体放电污水处理系统能快速去除有机废水中COD。A gas-liquid hybrid plasma discharge reactor with Dual-Water-Electrodes（DWEs） was proposed due to its many specific advantages in the organic wastewater treatment.Then,the discharging theory and the characteristics of the plasma reactor were analyzed.Furthermore,a prototype with 4.8 kV peak output voltage and 100 mA peak output current was built to degrade the phenol.Results show that the removal rate of chemical oxygen demand（COD） can reach 65% under the certain discharging conditions,and the amount of COD can be decreased rapidly by the plasma discharging wastewater treatment system with DWEs.
