摘　　要：文章利用介质阻挡放电(DBD)与Fe2+协同处理硝基苯废水,考查了外施电压、初始pH、处理时间及硝基苯初始质量浓度诸因素对去除率的影响,对降解产物进行GC/MS分析,结果表明,介质阻挡放电与Fe2+协同作用能有效降解硝基苯。产物分析表明DBD-Fe2+协同放电降解水相中有机物应在富氧条件下进行。DBD combined with Fe（II） can degrade nitrobenzene wastewater. Some parameters such as the applied voltage, original value of pH, discharge time and original concentration of nitrobenzene which influence the removal efficiency are investigated and the products are analyzed by GC/MS. The results show that DBD combined with Fe（Ⅱ）can improve the degradation of nitrobenzene efficiently. The study also shows that the degradation of organic wastewater by DBD combined with Fe（Ⅱ） should be conducted under the condition of abundant O2.
