摘　　要：为了提高放电等离子体水处理技术中的能量注入及处理效果,设计出一种耦合谐振放电电路,将脉冲电源产生的脉冲波形转化为耦合谐振波形,并将其产生的耦合谐振放电等离子体用于双反应器中罗丹明B溶液的降解,为同时对双反应器中的有害物质进行高压脉冲放电等离子体降解提供了一种放电波形支持;并采用分光光度法检测罗丹明B溶液的浓度。结果表明,耦合谐振放电可显著提升罗丹明B溶液的降解效果。放电降解60 min后,双反应器中的溶液降解率在不同放电电容配比下均可达到90%以上。耦合谐振放电注入反应器中的能量至少是无耦合谐振放电的7倍,其能量注入效率更高。此外,调整放电电路中的电容值可分别改变双反应器中注入的能量,进而影响到降解效果;反应器中溶液电导率越大,放电现象越明显。In order to enhance the energy injection and effect in discharge plasma water treatment, we designed a coupled resonator circuit. The circuit translates pulse waves generated from pulse power supply into coupled resonator waves.Therefore, the coupled resonator discharge plasmas were used to degrade rhodamine B solution in double reactors and to provide the plasma degradation of harmful substances with support of waveform. The concentration of rhodamine B solution was detected by spectrophotometry. The results indicate that the coupled resonator discharge can significantly enhance rhodamine B degradation.The degradation rate is at least 90% in the double reactors under various capacitance ratios after discharge of 60 minutes. The coupled resonator discharge can inject seven times more energy into the reactors than that without coupled resonator. Moreover, adjusting the electric capacity in discharging circuit can change the injected energy and consequently the degradation effect. In the double reactors, the discharge phenomenon becomes more obvious with increasing solution conductivity.
