摘　　要：采用Fenton试剂/活化凹凸棒石工艺去除模拟微污染水中的苯酚,考察了pH值、吸附时间、投加量等因素对苯酚去除效果的影响。结果表明,Fenton试剂与活化凹凸棒石联用对微污染水中的苯酚具有较好的去除效果,在苯酚浓度为10 mg/L、pH=8、温度为25℃、活化凹凸棒石投量为8 g/L、吸附时间为30 min的条件下,对苯酚的去除率达94.4%;活化凹凸棒石对苯酚的吸附行为符合Langmuir吸附等温方程。Fenton reagent and activated attapulgite are jointly used to remove phenol from simulated micro-polluted water. The effects of pH value, adsorption time and attapulgite dosages on the phenol removal rate were investigated. The results show that the combination of Fenton reagent and activated attapulgite has better removal efficiency of phenol from micro-polluted water. The removal rate of phenol reaches 94.4% when its initial concentration is 10 mg/L, pH value is 8, temperature is 25℃, activated attapulgite dosage is 8 g/L and adsorption time is 30 min. The adsorption of phenol by activated attapulgite fits the Langmuir adsorption isotherm equation.
