摘　　要：随着我国含铬化学产物的迅速发展,其产量和消费已跻身世界第一。铬不但对植物的生长有影响,而且还严重威胁人类的健康。因此,在各种重金属污染治理的研究中,铬污染治理一直是研究焦点之一。在化学修复技术、植物修复技术、微生物修复技术、电动修复技术等铬污染治理技术中,电动修复技术是一种新型原位修复技术,尤其适用于处理低渗透的土壤和污泥;它具有投资少、效率高、无二次污染等优点。本文阐述了电动修复除铬的技术原理,结合近年来国内外关于电动修复技术应用于铬污染土壤和污泥治理的研究文献,对电动修复技术的影响因素及强化措施进行了分析和综述,并提出了当前研究存在的问题和建议,最后展望了电动修复应用于治理铬污染的发展趋势。With the rapid development of chromium chemical products in China, the production and the consumption have firmly be- come the first in the world. Chromium not only has an effect on the growth of plants, but also has a serious threat to human health. Therefore, the removal of chromium pollution is always the focus of heavy metal remediation. Electrokinetic remediation is a promising in-situ technology among chemical remediation, phytoremediation, bioremediation and electrokinetic remediation, which is of less in- vestment, high efficiency, no secondary pollution and is suited to remediate fine-grained soil or sludge. The objective of this article was to expound the theoretical of Cr removal from soil or sludge, then analyze and overview the influencing factors and the enhancement techniques of electrokinetic remediation by combining domestic and international researches on removing of Cr from contaminated soil or sludge by electrokinetic. Meanwhile, when consolidating the thoughts and findings of past researches, some disadvantages and sugges- tions were given. At last, the prospects on electrokinetic remediation applied to removing Cr were proposed.
