土壤重金属污染现状与治理途径研究进展

Current Situation of Soil Contaminated by Heavy Metals and Research Advances on the Remediation Techniques

分析了我国土壤重金属污染现状,阐明了土壤重金属的危害,介绍了当前污染土壤的各种修复措施,包括工程修复措施、物理化学修复措施、化学修复措施、农艺调控措施以及生物修复措施等;对各种措施的修复原理、已取得的研究进展以及优缺点进行了分析,并提出土壤重金属污染物防治必须重视管理措施的发展和应用。最后对土壤污染防治存在的问题和今后研究的方向进行了探讨。

In this paper the harm of heavy metals in soil and current situation of soil contaminated by heavy metals were discussed, and then the rerrdiation technologies of heavy metals contanfinated soils, which included physical-chemical remediation methods, chemical remediation methods , agriculture remediation methods and bioremediation methods at home and abroad were roundly introduced The management methods should play a key role in remadiating soils contanfinated by heavy metals. At the same time, advantages and disadvantages of every remediation technology and their future development were reviewed. At last, the directions for further research on the remediation techniques were pointed out.
