摘　　要：对脉冲流光放电与活性炭或活性炭纤维联合处理废水时活性炭和活性炭纤维的催化作用进行了研究。结果表明:脉冲流光放电与活性炭或活性炭纤维联合处理,降解率分别提高22%和24%,说明联合处理过程具有协同效应。与吸附饱和的活性炭或活性炭纤维联合处理,降解率分别提高12.25%和16.7%,说明活性炭和活性炭纤维在联合处理过程中起催化作用。联合处理过程中加入H2O2,不但提高了O3和UV的利用率,而且还提高了活性炭和活性炭纤维的再生率。Catalysis of granular activated carbon and activated carbon fiber were investigated in high voltage pulsed discharge wastewater treatment. The experimental result shows that the removal efficiency of methyl orange can be enhanced by 22% and 24% respectively in combined treatment of pulsed streamer discharge and granular activated carbon or activated carbon fiber. The degradation rate can be enhanced by 12. 25% and 16. 7% respectively with and without saturated granular activated carbon or activated carbon fiber in discharge. This indicates that the catalytic activity of activated carbon fiber is more advantageous. In addition, regeneration of granular activated carbon and activated carbon fiber can be achieved in this process.
