摘　　要：电动修复技术是近几年发展起来的一种新型土壤修复技术,由于其处理的高效性受到了越来越多的关注。本文介绍了利用电动技术强化土壤有机污染物原位修复的原理及其最新进展。电动强化有机物污染修复的基本原理是利用电动效应对有机物的迁移作用或者强化生物修复过程(注入营养物、电子受体和活性微生物等)达到去除污染物的目的。研究表明,该技术不破坏生态环境,安装操作简单成本低廉,具有广泛的应用前景,其中电动强化原位生物修复和能够适应于各种不同成分污染(如有机物-重金属复合污染)的多技术联合是今后电动技术发展的重要方向。Electrokinetic enhancement of in situ remediation is a new and innovative technology. Because of its high efficiency in removing contaminants from soil and groundwater, in recent years, electrokinetic remediation has been paid more and more attention to. This paper reviewed the principle of enhancement of in situ remediation of soils contaminated with organics by electrokinetics and its newest advances in research and applications, expatiated on the advantages of this technology over other technologies, pointed out the obstacles to overcome in using this technology, and discussed the possibilities in full-scale commercial applications. The electrokinetics is able to, by use of electroosmosis, electromigration and electrophoresis, control the transport of pollutants toward a certain direction in subsurface or enhance the bioremediation process （inject nutrients, electron acceptor, active microbe）. It is effective, no damage to the environment, simple in installation and operation, much cheaper, and thus has great potential for application. Electro-bioremediation and combined technologies are the most promising ones.
