活性炭在气液串联放电反应器中的作用

对气液串联放电反应器中悬浮活性炭对降解有机污染物的影响及联合处理过程中活性炭的作用进行了研究。结果表明：46kV脉冲流光放电与5g／L水洗活性炭联合处理具有协同效应，甲基橙的降解率提高22％；与5g／L吸附饱和的活性炭联合处理，比单独脉冲放电处理降解率提高12．25％，说明活性炭在联合处理中不仅有吸附能力，而且还具有催化作用。在上述两种条件下分别加入5ml／L H2O2，对·OH的产生具有协同效应，不但提高了O3和UV的利用率，而且还有利于活性炭的再生。

The role of activated carbon in gas-liquid series electrical discharge reactor

The effects of activated carbon in gas-liquid series electrical discharge reactor for the degradation of organic contaminants and the function of activated carbon in combined treatment were investigated. The result shows that the degradation efficiency of methyl orange can be enhanced 22% and the synergetic effect can be emerged with the combined treatment of 46 kV pulse streamer discharge and 5g/L activated carbon. The degradation efficiency can be enhanced 12.25% with addition of 5 g/L saturated activated carbon than without in discharge, this case shows that activated carbon not only have adsorption capacity but also have catalysis. With the addition of H2O2 in the above-mentioned two kinds of conditions, synergistic effects can be generated for formation of Hydroxyl radical and that utilization ratio of O3 and UV are raised. Furthermore, it is also helpful to the regeneration of activated carbon.
