活化凹凸棒石联合Fenton试剂处理水中苯酚

Study on Treatment of Phenol in Micro-polluted Water by Fenton Oxidation and Activated Attapulgite Adoption

采用Fenton试剂联合活化凹凸棒石处理模拟微污染水中苯酚。在Fenton试剂氧化处理的最佳条件下对活化凹凸棒石吸附苯酚的最佳条件进行了研究,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:使用Fenton试剂氧化处理后再用活化凹凸棒石对微污染水中苯酚具有较好的去除效果,在苯酚浓度为10mg/L、pH8、温度为25℃、投加量为8g/L、吸附时间30min的条件下,苯酚去除率达94.40%;

Using combined process of fenton reagent and activated attapulgite treat phenol of micro-polluted water,the best reaction conditions of attapulgite adsorption were studied under the best Fenton oxidation conditions.The effects of pH value,adsorption time,attapulgite dosages,etc.on the elimination of phenol through adsorption were investigated.The results showed that the removal rate of phenol in micro-polluted water can meet 94.40% under the conditions,for an initial phenol concentration in water sample of 10 mg/L,pH value 8,temperature 30 ℃,8 g/L of the activated attapulgite and 30 min of adsorption time.
