| 摘 要： | 用超声波和Fenton试剂耦合处理农村垃圾的渗滤液,考察了超声波功率、H2 O2和Fe2+用量、pH值以及反应温度对农村垃圾渗滤液UV254/UV254o的影响。研究结果表明:超声功率为125 W,H2 O2浓度为475 mmol/L,Fe2+浓度为4 mmol/L,pH值为3.0时,农村垃圾渗滤液中的难降解有机物能够得到较好的去除,超声-Fenton试剂耦合处理农村垃圾渗滤液的温度应该控制在45℃以内;通过超声、Fenton和超声-Fenton试剂耦合对比实验发现,超声-Fenton试剂耦合对农村垃圾渗滤液中难降解有机物的去除要明显好于Fenton试剂和超声波,超声波和Fenton试剂对农村垃圾渗滤液中有机物的去除具有协同作用。光谱扫描结果表明,超声-Fenton试剂耦合对农村垃圾渗滤液中的有机物有很好的去除效果。

| Abstract: | The treatment of landfill leachate in rural areas was carried out by ultrasound-Fenton reagent progress.The effect of operating conditions such as ultrasoundpowers,Fenton’s reagent dosage,pH value and the reaction temperature on UV254 /UV254o was investigated.The experiment results indicated that ultrasound-Fenton reagent progress can effectively remove refractory contaminants under the optimal conditions with ultrasonic power of 125 W,H2O2 concentration of 475 mmol/L,Fe2+ concentration of 4 mmol/L and pH value of 3.0.The reaction temperature was control within 45℃.Ultrasound process,Fenton reagent and Ultrasound-Fenton reagent progress were compared.The results showed that Ultrasound-Fenton reagent progress achieved more refractory contaminants removal rate than Ultrasound process and Fenton reagent.Ultrasound-Fenton reagent progress had an obvious synergistic effect for the removal of refractory contaminants.The result of UV-vis spectra of landfill leachate in rural areas showed that Ultrasound-Fenton reagent progress is an effective method for removal of organic compounds. |
