摘　　要：研究了超声波降解水中二甲苯的降解效果,详细探讨了反应容器及沸石、声强、超声时间、H2O2投加量、温度、pH值等因素对降解二甲苯的影响.实验结果表明:二甲苯初始质量浓度为27.6mg/L,H2O2的质量浓度为1.68g/L,温度为24±1℃时,经141.32W/cm2声强辐射1h,其降解率可达99.2%.The effects of reaction vessel , sonic intensity , sonication time,initial concentrations of H_2O_2 ,solution temperature and pH on ultrasonic degradation of xylene were studied.The results indicated that the average degradation of xylene could come up to 99.2% under the following reaction conditions: 27.6 mg/L of xylene concentration,1.68 g/L H_2O_2 concentration,(241) of temperature,141.32 W/cm^2 of sonic intensity and 1 h of irradiation.
