摘　　要：采用Fe2+/活性炭非均相Fenton试剂催化处理高浓度模拟苯酚废水。以体积分数为40%的硫酸对颗粒活性炭进行预处理后加入质量分数为10%的硫酸亚铁溶液,制备Fe2+/活性炭。在非均相Fenton试剂氧化体系中,Fe2+/活性炭初次使用时,苯酚去除率为92%;连续重复使用5次,苯酚去除率仍可达53%。Simulated phenol wastewater with high concentration was treated by heterogeneous phase Fenton reagent oxidation process with Fe^2＋/activated carbon catalyst. Fe^2＋/activated carbon catalyst was prepared by pretreating activated carbon particles with sulfuric acid （40% of volume fraction） and then adding them into ferrous sulfate solution with 10% of mass fraction. In the heterogeneous Fenton reagent oxidation system, the removal rate of phenol is 92% for the first time of use, and still can reach 53% after 5 times of reuse.
