污染土壤修复技术研究进展

A Review on the Progresses of Remediation Technologies for Contaminated Soils

土壤是人类生产活动的重要物质基础,随着社会经济的高速发展和高强度的人类活动,土壤受污染面积不断扩大,土壤质量持续恶化,影响到实现可持续发展的战略目标。由土壤污染导致的农产品的生态安全问题已不容忽视。因此,开展污染土壤修复活动,完善土壤修复技术体系,对阻断污染物进入食物链,防止对人体健康造成危害,实现社会经济可持续发展是非常重要的。该文系统介绍了目前国内外污染场地修复中广泛使用的物理修复技术、化学修复技术、生物修复技术(包括植物修复、微生物修复和动物修复技术)以及相关技术结合使用的联合修复技术,并对各种方法的研究进展进行了较全面的综述,最后也对未来土壤污染修复技术的发展方向进行了展望。

The development of modern agriculture has been affecting natural environment.The conditions of contaminated soils are getting worse due to fertilizer and chemical pesticides used in great quantities,making remediation of pollutants contaminated soils as the pressing issue.We give a systematical introduction to the technologies for remediating contaminated soils being widely used at home and aboard,especially the physical remediation technologies,chemical remediation technologies, bioremediation technologies（including phytoremediation,microbial remediation and soil fauna remediation technologies）and other remediation methods incorporating technologies mentioned above.In addition,a relatively comprehensive review is done on the research progress of various remediation technologies followed by the outlook on the future development of remediation technologies of contaminated soils.
