摘　　要：电动修复技术是近年来发展起来的一种用于处理土壤污染的绿色技术,现已成为当前土壤修复研究领域的热点。综述了电动修复去除污染物的反应机理和优缺点,影响电动修复效率因素如土壤性质、电压梯度、电极材料、两极p H等,并总结了近年来治理重金属、有机物多类型复合污染土壤的电动修复及电动-淋洗、电动-生物、电动-超声、电动-PRB联合技术的研究进展,提出了此类技术的发展前景以及方向。Electrokinetic remediation（ EK） is widely regarded as a green technology to deal with the contaminated soil,and becomes the research focus in the field of soil remediation. This review introduced the EK principles applied in remediation of the polluted soil,the advantages as well as limitation,and the factors influencing the EK efficiencies such as soil properties,voltage,electrode materials,p H of electric poles,etc. It summarized the recent studies on removal of soil co-contaminants like heavy metals and organic compounds by using EK and combined technology such as EK-Flushing,EK-Bioremediation,EK-Ultrasound,EK-PRB,and finally proposed the prospects and future trend of EK.
