摘　　要：以甲基橙溶液模拟废水为研究对象,采用自制复频超声波污水处理装置,研究复频超声、氯盐对甲基橙脱色率及COD去除率的影响,改变超声频率、功率、作用时间及甲基橙初始含量、氯盐种类、投入量,用分光光度法检测,考察对脱色率的影响。结果表明,频率越高、复频范围越宽,脱色率、COD去除率越高;加入氯盐后影响显著,脱色率、去除率可达95%以上。采用复频超声并添加CaCl2处理甲基橙模拟废水的效果最佳。In this paper, the effects of multi-frequency ultrasonic and chlorine-salt on decolorization rate and COD removal efficiency of methyl orange were studied. The effects on decolorization rate by using self-made sewage treatment device with multi-frequency ultrasonic, changing ultrasonic frequency, power, reaction time and the original concentration of methyl orange, chlorine-salt type and adding amounts, and using spectrophotometric detection were analyzed. The results showed that： the higher the frequency, the wider frequency range, the decolorization rate and COD removal efficiency were higher; the effect of chlorine-salt was remarkable, and the decolorization rate and removal efficiency were above 95%. Under multi-frequency ultrasonic, the impact of CaCI2 was the greatest.
