| 中文摘要: |
| 本文以硝基苯模拟废水为研究对象,探讨了超声波与电化学协同作用降解硝基苯的实验情况。考察了处理时间、处理温度、硝基苯初始浓度、pH值、电解电压等因素对硝基苯降解率的影响。实验结果表明:随着作用时间增加,硝基苯的降解率升高;温度高于40℃时,硝基苯的降解率随温度的升高而降低,低于40℃时,硝基苯的降解率随温度的升高而增大;硝基苯的降解率随电压的升高而增大;酸性条件有利于硝基苯的降解;硝基苯初始浓度越大降解率越高。 |
| 英文摘要: |
| The effects of irradiation time, concentration of nitrobenzene solution, pH, temperature and voltage on the degradation efficiency of nitrobenzene by electrochemical oxidation with ultrasound were studied. The results show that the degradation efficiency of nitrobenzene solution increases with the increasing of irradiation time; the degradation efficiency of high concentration nitrobenzene solution is better than that of the low; the degradation efficiency of nitrobenzene decrease with the increasing of pH, the degradation efficiency of the nitrobenzene increases at first, then decreases with the increasing of temperature; and is the highest at about 40℃; with the voltage between the electrodes growing from 15V to 30 V, the degradation efficiency of nitrobenzene solution increases. |
