六氯苯污染沉积物的电Fenton法处理

Study on electro-Fenton treatment of HCB-containing sediment

研究了牺牲阳极电Fenton工艺对被六氯苯污染的沉积物进行处理的方法 ,分析了电Fenton方法对河流沉积物中六氯苯的去除能力 ,研究了该方法的影响因素 ,以探索河流沉积物修复的新途径 .试验结果显示 :以不锈钢片作为电极对模拟沉积物进行电Fenton处理 ,在外加电压 15V、初始 pH值为 3的条件下 ,2h处理后六氯苯的去除率可达 5 6 .7% .

The electro Fenton oxidation of Hexachlorbenzene (HCB) in simulated sediment was studied. The removal efficiency of HCB was optimized in the electro Fenton system and a new resolution was proposed for sediment remediation. The results of the experiments indicated the removal efficiency of HCB after electro Fenton oxidation process for 2h could be more than 56.7?%. The results showed that the electro Fenton method was an available process for remediation of HCB containing sediment under the optimized conditions of initial pH=3, voltage=15?V, and stainless steel slice electrode.
