| 摘 要： | 通过正交实验确定影响超声波降解硝基苯的因素,探讨了在超声条件下反应温度、超声频率、处理时间对硝基苯降解的影响;并对超声/H2O2、超声/H2O2/CuO体系对硝基苯的降解效果进行了初步研究.结果表明:在超声条件下,当硝基苯初始质量浓度为150.8mg/L、超声频率为40kHz、作用时间为6h时,硝基苯的降解率为18%;在超声/H2O2条件下,H2O2投加量为3.0mL时,降解率可提高至22.3%;向超声/H2O2体系中加入CuO可使硝基苯的降解率提高到38.7%.

| Abstract: | The factors of influencing the degradation rate of the nitrobenzene contained in wastewater such as reaction temperature,ultrasonic frequency and treating time are studied through orthogonal experiments.The effects of ultrasound/H2O2 and ultrasound/H2O2 /CuO on the degradation of nitrobenzene are also investigated.The results show that when the initial concentration of nitrobenzene is 150.8 mg/L,ultrasonic frequency is 40 kHz,treating time is 6 h,the degradation rate of nitrobenzene reaches 18% by using ultrasound alone,it can be increase to 22.3% under ultrasonic/H2O2 when the dosing quantity of H2O2 is 3.0 mL,and it can be increased to 38.7% when CuO is added to the ultrasonic/H2O2 system. |
