摘　　要：采用电动力学方法对六氯苯污染的底泥进行修复研究,分析了底泥中六氯苯的迁移特性,研究了影响六氯苯去除效果的因素.同时通过正交试验,分析了各影响因素的显著性水平,确定了电动力学修复的最佳工作条件:以不锈钢片为电极,电极间距为80mm,在外加电压15V,电解质NaCl投加量5g,初始pH值为1.0,经过6h的处理后,六氯苯去除率可达58.8%.The electro-kinetic remediation of Hexachlorbenzene （HCB） contaminated simulated sediment was studied. The mobilization characteristics of HCB in sediment and its affecting factors were investigated. By orthogonal test, the significant value of each affecting factor was analyzed. The removal efficiency of HCB after electro-kinetic remediation for 6 h could be more than 58.8% on the optimum conditions that voltage 15 V, electrolyte （NaCl） dosage 5 g and initial pH 1.0 and stainless steel slice electrode （80 mm divided）.
