摘　　要：将微波与催化湿式氧化技术相结合,以载铜活性炭为催化剂,间歇式处理高浓度对硝基酚废水.实验结果表明,对于初始浓度为1000mg·L-1的高浓度对硝基酚废水,最佳反应条件为固液比1∶1、空气量160mL·min-1和微波功率234W.在最佳条件下,废水中对硝基酚去除率为75%.气质谱分析对硝基酚中间降解产物为苯酚和羟基氧化物等.In this paper,p-nitrophenol（PNP） wastewater with high concentration was treated in a batch reactor by microwave technology combining catalytic wet air oxidation（CWAO） ,using carbon-supported copper catalyst. The results show that the optimal reaction parameters were solid-liquid ratio of 1∶1,air flow 160 mL·min-1 and the microwave power 234 W for the treatment of PNP wastewater with initial concentration 1000 mg·L-1. The average removal efficiency of PNP in wastewater reached 75% under the optimal conditions,and phenol and hydroxyl oxides were determined as intermediate products by GC-MS.
