铅污染土壤的修复技术

Lead-Contaminated Soil Remediation Technologies

土壤铅污染是目前较为突出的环境问题,而且国内近几年有加重的趋势。为此,国内外对土壤铅污染的修复技术进行了大量的研究。文章主要综述了铅对土壤的污染及其修复技术,主要包括物理化学修复、生物修复、农艺修复、工程修复等技术。同时对铅污染修复的发展方向进行了展望,为土壤铅污染的修复技术研究提供了借鉴和参考。

Lead contamination in soil is more prominent environmental problems, and there is a tendency to increase at home in recent years. So, Lead-contaminated soil at home and abroad have done a lot of repair technology research. The paper summarizes the lead on soil pollution and remediation technology, including physical and chemical restoration, bioremediation, agronomic repair, engineering and repair techniques. At the same time lead to the development direction of the remediation prospected, providing a useful reference for the study of lead-contaminated soil remediation technologies.
