Abstract: The degradation of phenol in aqueous solution by the dual-frequency ultrasound technology and the major affecting factors such as sound intensity, pH value of solution, initial concentration and medium temperature are studied.The results show that the dual-frequency ultrasound technology is superior to single frequency ultrasound technology in degradation of phenol.Within half an hour, the phenol removal rate by using dual-ultrasonic irradiation is obviously higher than the sum of the removal rates by using two separate single frequency ultrasonic irradiations.The synergetic effect of dual-frequency ultrasound is significant. In addition, adding Fenton reagent could accelerate the phenol removal rate.

摘要: 研究了复频超声波氧化降解水中苯酚的降解效果,并且详细探讨了影响复频超声波降解苯酚的影响因素.实验结果表明:复频超声波处理苯酚去除率远比单独22 kHz和单独40 kHz超声波处理效率之和还大,复频超声波氧化技术具有明显的协同效应,苯酚降解速率提高了1.5倍.另外在实验中通过加入Fenton试剂能够加速苯酚的降解.
