摘　　要：以芬顿试剂为催化剂，辅助紫外辐射和超声辐照，对模拟苯酚污水进行了初步实验研究．研究结果表明超声波单独作用时，弱碱性条件（pH=8．2）下有利于苯酚的降解；芬顿试剂单独作用时强酸性条件（pH=3．2）下有利反应的进行；二者联合作用时具有协同效应．The degradation of phenol in agueoas solution by the combinative method of uhrasound/UV- Fenton were investigated. The experimental results showed that the degrees of phenol degradation were best by only using ultrasound under the condition of pH=8.2,while by only using Fenten agent under the condition of pH = 3. 2. Furthermore, the combination process of ultrasound conjugating UV-Fenton reagent could effectively degrate the phenol pollutants in the wastewater. The COD degradation efficiency of the joint-process was high than the each process alone.
