摘要
土壤中,重金属来源广泛,一旦含量超标,就会造成极大危害。本文首先分析了多种修复重金属污染土壤的技术,然后重点探讨植物修复技术,包括植物萃取、植物挥发、植物固定、根际圈生物降解等方法。根据植物修复技术的优缺点,笔者进一步阐明了植物修复技术在修复重金属污染土壤时存在的问题,并提出解决方案。
In soil,there are a wide range of sources of heavy metals,once the content exceeds the limit,it will cause great harm.This paper first analyzes a variety of techniques for remediation of heavy metal contaminated soil,and then focuses on phytoremediation techniques,including plant extraction,plant volatilization,plant fixation,and rhizosphere biodegradation.According to the advantages and disadvantages of phytoremediation technology,the author further clarified the problems existing in phytoremediation technology in remediation of heavy metal contaminated soil,and proposed solutions.
