摘要: 采用超声与氧化技术联合处理糠醛废水,其COD去除率可达87%,同时考察了反应时间、温度、初始浓度、超声频率、超声功率、H2O2和FeSO4初始浓度等工艺参数对COD去除效果的影响,为处理该种废水提供了一种清洁、简便、低能耗的净化方法。Abstract: The laboratory scale treatment of furfural wastewater by ultrasound wave and hydrogen peroxidhas was studied, with COD removal efficiency of 87%. The effects of the process’s parameters (reaction time, temperature, wastewater concentration, frequency and power of supersonic, dosages of H2O2 and FeSO4) were also investigated. The combination is one kind of clean, easy-operated and low-cost purified method for this kind of wastewater.
