摘要
近年来土壤污染日益严重,由无机污染物(重金属、放射性元素等)和有机污染物(多环芳烃等)污染的土壤已经对人类健康和生态环境构成风险,引起了广泛关注。电动修复技术(Electrokinetic remediation,EK)是一种可原位修复污染土壤的技术,由于其对污染场地修复的高效性,现已成为污染场地修复的研究热点。综述了电动修复技术的原理、优缺点,电动-植物、电动-微生物、电动-可渗透反应墙(Permeable reactive barrier,PRB)、电动-淋洗等电动联用技术修复污染场地土壤的研究进展,并总结了实际污染场地修复对土壤理化性质的影响,提出了该项技术的发展趋势和研究方向。
In recent years, soil pollution has become increasingly serious. The soil polluted by inorganic pollutants(heavy metals, radioactive elements, etc.) and organic pollutants(polycyclic aromatic hydrocarbons, etc.) have posed risks to human health and ecological environment, which has attracted widespread attention. Electrokinetic Remediation(EK) is a technology for in-situ remediation of contaminated soil. Due to its high efficiency in the remediation of contaminated sites, it has become a research hotspot in the remediation of contaminated sites. This paper reviewed the principle, advantages and disadvantages of electrokinetic remediation technology, the current research progress of EK-Phytoremediation, EK-Bioremediation, EK-PRB,EK-Flushing combined technologies for remediation of contaminated site soil, and summarized the influence of actual contaminatedsite remediation on soil physical and chemical properties, put forward the development trend and research direction of this technology.
