摘要
采用超声与Fenton高级氧化技术联合处理染料废水,取得了满意的效果。同时考察了初始浓度、初始pH值、超声时间、超声频率、超声功率、H2O2和FeSO4初始浓度等因素对其COD去除效果的影响,当超声波频率为45 kHz,功率为200 W,初始pH值为2.63,超声时间为150 min,H2O2浓度为60 mmol/L,FeSO4浓度为12 mmol/L时,染料废水COD去除率达到91.8%。
The laboratory scale treatment of dye industry wastewater by ultrasound wave coupling Fenton process was studied. The effects of the process＇ s factors （wastewater concentration, pH, reaction time, frequency and power of supersonic, amount of H2O2 and FeSO4） were also investigated. The COD removal rate of dyes wastewater surpassed 91.8% after 150 min reaction under the experimental conditions：ultrasonic frequency of 45 kHz , output power of 200 W, pH of 2.63, amount of 60 mmoL/L H2O2 and 12 mmol/L FeSO4 and room temperature.
