重金属污染土壤的修复技术研究

Technology on Remediation of Soils Contaminated by Heavy Metals

土壤污染已经成为一个全球性的环境问题之一,而重金属污染在土壤污染中占有很大的比重,对人类生产和生活以及生态环境造成很大的威胁。文中先针对造成土壤重金属污染的原因进行了分析,后从工程措施、物化修复、化学修复、生物修复、自然修复、及组合修复技术等几个方面分别阐述了重金属污染土壤的修复技术及其研究进展,给出了今后进行重金属污染修复的建议。

Soil pollution has become one of the global environmental problems, in which contamination by heavy metals occupied much proportion and has a very serious threat to the human＇s life and the entiromnent.This article analyses the reason which causes the heave mental pollution at first,then elaborates the remediation technology and research progress of the contaminated soils by heavy metals from engineering measures, physical chemical remediation, chemical remediation, bioremediation,nature remediation, and their combination. Meanwhile, it also Comes up with some suggestions about the remedition methods for soil heavy metal contamination applied in the furture years.
