摘要: 研究了在气液固三相流化床内使用Fenton 试剂、H103树脂氧化吸附组合联用处理模拟含酚废水的新工艺。探讨了pH值、反应温度、反应时间、气流速度、树脂固含率等因素对苯酚去除率的影响。实验结果表明:在模拟含酚废水pH=4、苯酚质量浓度为100 mg/L、通气量为0.12 m3/h的条件下,当单纯采用氧化法处理,在温度为60 ℃、反应30 min后,苯酚去除率为95.67%;而采用氧化吸附组合法,在温度为 30 ℃、树脂固含率为4%、反应25 min后,苯酚去除率能够达到99.52%。

Abstract: The efficiency of Fenton agent combined with macroporous resin H103was examined using phenol as a model compound in simulated wastewater in a gas-liquid fluidized bed.A batch study was conducted to optimize parameters like the pH、temperature、reaction time,velocity and solid holdup governing the process. The experimental results indicated that the phenol removal rate was 95.67% only using the oxidation process at 60 ℃,pH= 4,ventilation volume of 0.12 m3/h,after reaction time of 30 min .the phenol removal rate was 99.52% using the oxidation combined with adsorption process at 30 ℃,pH= 4,the resin solid holdup rate of 4%,ventilation volume of 0.12 m3/h,after reaction time of 25 min. At this point the concentration of phenol was 100 mg/L.

Key words: phenol wastewater, Fenton reagent, macroporous resin, phenol removal rate
