摘要
有色金属尾矿具有金属含量高、酸碱性强、养分含量低等制约植物修复的不利因素,采用科学合理的强化技术可以提高植物修复的效率。归纳了添加基质、化学诱导、基因工程以及接种根际微生物4种强化植物修复尾矿的技术,分析了不同植物强化技术对尾矿修复的机理,并展望了植物修复强化技术在有色金属尾矿治理方面的发展方向和前景。
Non-ferrous metal tailings have high metal content,strong acidity and alkalinity,low nutrient content,and other unfavorable factors that restrict phytoremediation.However,some scientific and reasonable intensification technologies can improve the efficiency of phytoremediation.This paper summarizes four technologies for enhancing phytoremediation of tailings by adding matrix,chemical induction,genetic engineering and inoculation with rhizosphere microorganisms,and analyzes the mechanisms of different plant strengthening technologies for tailings phytoremediation.Finally,the development direction and prospect of phytoremediation technologies for tailings remediation are prospected.
