摘　　要：对超声波、紫外光协同氧化方法处理酸性红B染料废水进行了研究,探讨了水样初始浓度、初始pH值对其脱色效率的影响。并在各条件下,对超声波、紫外光单独作用和两者协同作用下的结果进行了对比。结果表明,超声波与紫外光的协同作用效果明显,染料的降解过程符合准一级动力学方程。在温度30℃、初始浓度50mg/L、pH=11.5、饱和气体为氧气、紫外光波长为253.7nm时,酸性红B经协同处理60min,脱色率可达99.1％。Study on treatment of acid red B wastewater by combination of ultrasound and ultraviolet, and ap-proach on the effects of initial concentration and pH value on decolorization efficiency of dyestuff wastewa-ter, and effects obtained by ultrasound, ultraviolet and combination of both respectively were compared under different conditions have been conducted. The result indicated that combination of ultrasound and ultraviolet enhanced decolorization greatly. The degradation process of acid red B follows pseudo-first-order ki-netic equation. Under preferable conditions of tem-perature 70℃, initial concentration 50mg/l,pH 11.5, saturating with oxygen and ulltraviolet wavelength 253.7nm, 99.1% of color could be removed after 60 minutes photosonochemical degradation.
