研究了在气液固三相流化床内使用Fenton试剂与H-103树脂组合联用处理模拟含酚废水的新工艺。探讨了pH值、反应时间、树脂固含率、H2 O2和Fe2＋的初始浓度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1000 mg/L、温度为25℃、通气量为0．12 m3/h的条件下，单纯采用吸附法处理，苯酚去除率为86．3％；单纯采用氧化法处理，苯酚去除率为95．5％；而采用氧化-吸附组合法，苯酚去除率能达到98．7％。组合法对苯酚的去除效果明显优于单一方法。

The new process for phenolic wastewater treatment using Fenton agent combined with macroporous resin H-103 was studied.The effect of pH,reaction time,resin solid holdup rate and [H2 O2 ]and [Fe2+]initial concentrations on the phenol removal rate was explored.The experimental results indicate that the phenol removal rate is 86.3% and 95.5% for single adsorption and the Fenton oxidation process alone,respectively.However, the removal rate of 98.7% can be obtained when using the oxidation-adsorption combination process at 25 ℃, pH=4,ventilation volume of 0.12 m3/h.The concentration of phenol in wastewater is 1 000 mg/L.It is obvious that the efficiency of phenol removal by using the oxidation-adsorption process is better than that of the single methods.
