| 摘 要： | 采用超声辅助光催化氧化法（US／UV／Ti02）对活性艳红X-3B模拟废水进行降解处理。考察了降解条件对活性艳红X-3B废水处理效果的影响，确定了处理50mg/L活性艳红X-3B染料废水的最佳条件：催化剂TiO2用量0．5g／L、H2O2投加量1．98mL／L、废水pH值为9、曝气量0．8L／min，在此条件下，光照60min，活性艳红X-3B降解率可达98．3％。与单一光催化氧化法（UV／TiO2）相比，US／UV／TiO2降解效果具有明显优势，说明超声和光催化具有很强的协同效应。

| Abstract: | The reactive brilliant red X -3B dyeing simulated wastewater was treated by UV photocatalysis system assisted with ultrasonic （US/UV/TiO2 ）. The affects of degradation conditions on treatment effect of X- 3B were investigated and the optimum treatment conditions for the 50 mg/L X- 3B dye wastewater were determined as follows： amount of catalyst TiO2 0.5 g/L, amount of H2O2 1.98 mL/L, pH value of the wastewater 9, aeration intensity 0.8 L/min. The degradation rate of X - 3B was up to 98.3% under above conditions and lighting time 60 min. The US/UV/TiO2 system had better degradation effect compared with UV photocatalysis system （UV/TiO2 ）, which showed sonolysis and photocatalysis had strong synergetic effect. |
