重金属污染土壤修复技术及其研究进展

Technology and Research Progress 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植物生长造成很大的威胁。本文从物化修复、化学修复、植物修复以及微生物修复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。同时还介绍了复合污染中重金属的研究进展,指出了重金属复合污染土壤修复的研究方向。

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 plant growth. This article elaborates the remediation technology and research progress of the contaminated soils by heavy metals from physical - chemical remediation, chemical remediation, phytoremediation and bioremediation. Meanwhile, it also introduces the research on the combined pollntion and points out the direction for the remedition of combined polluted soils.
