生物修复技术处理重金属污染土壤的研究进展

Research progress of bioremediation technology in the treatment of heavy metal contaminated soil

随着重工业的迅速发展,土壤的重金属污染问题已经成为目前一项重要的环境问题,对自然生态和人类健康形成巨大威胁。不同的修复技术如物理法、化学法和生物法已经被用于从环境中去除重金属污染物。生物技术是去除土壤中重金属(及其胶体)的最佳方法之一,其主要包括植物修复技术和微生物修复技术两大类。

With the rapid development of heavy industry,the pollution of heavy metals in soil has become an important environmental problem at present,posing a huge threat to natural ecology and human health.Different remediation techniques such as physical,chemical and biological methods have been used to remove heavy metal pollutants from the environment.Biotechnology is one of the best methods to remove heavy metals(and colloids)in the soil,and it mainly includes two categories:phytoremediation technology and microbial remediation technology.
