摘　　要：以CuO-MnO2-CeO2/C为催化剂,对COD=9000mg·l-1,NH3-N=700mg·l-1的模拟苯胺废水进行实验,讨论了催化剂用量对实验的影响,以及pH值和温度对COD及NH3-N去除率的影响.结果表明,在T=225℃,pH=10.03时,用湿式催化氧化法(CWO)处理1h后,苯胺废水中COD的去除率高达90%左右,NH3-N的去除率可达94%以上.利用水热电催化氧化法,以RuO2/Ti为电极,NaCl为电解质,在相同条件下,135℃时COD和NH3-N的去除率都可达到96%以上.This dissertation focuses on the treatment experiment of aniline wastewater analog, which consists of the prepared CuO-MnO2-CeO2/C and the aniline wastewater （configured COD = 9000mg · l^-1, NH3-N = 700 mg·l^-1） . The result indicates that the settings that T =225% and pH = 10. 03 are available, the removal rate of COD and NH3-N can reach 90 % and 94 % respectively after one hour＇ s catalytic wet oxidation （CWO） aniline reaction. Further more, by combining the CWO and electrochemical oxidation technology and utilizing the hydro-thermal electrolysis, the new device can be designed. With the self-made the RuO2/Ti electrode in NaCl electrolyte, under the identical condition, both the COD ＆ NH3-N removal rate of aniline wastewater at 135℃（configured COD =9000mg·l^-1, NH3-N =700 mg·l^-1） can scale above 96%.
