摘　　要：采用气相沿面放电等离子体反应器降解水中对硝基苯酚(PNP).考查了载气流量、氧气体积含量和溶液初始pH值对PNP降解效果的影响.结果表明:PNP的降解率随着载气流量的增加而增加,当载气流量增加到1.50 m3/h时,PNP的降解率可达90%以上;载气中氧气体积含量为41%时,PNP降解率为99%;pH值为弱碱性时,PNP的降解率为96%,明显高于pH值为中性和弱酸性时PNP的降解率,此时,COD去除率为74.5%,COD去除的能量利用率为8.86×10-3 mg/J.The degradation of p-Nitrophenol （PNP） in water using a gas phase surface discharge reactor was researched. The effects of the operating parameters, such as air flow rate, oxygen content and pH Value of initial solution on the degradation were discussed. The results show that the PNP degradation efficiency increases with the flow rate of the carrier gas; the optimal gas flow rate is 1.50 m^3/h under which the degradation of PNP reaches 90% ; when the oxygen content is 41% in the carrier gas, the degradation efficiency of PNP achieves 99% ; under alkaline conditions, about 96% of p-Nitrophenol is degradated, which is higher than those obtained under acid and neutral conditions; the removal of COD of PNP is about 74. 5% , and the energy efficiency of the removal of COD is up to 8.86×10^-3 mg/J.
