尾矿治理中植物修复技术研究进展

Advance of Phytoremediation Technology in Tailings Treatment

近年来,随着经济的不断发展,矿业开发的规模日益增大,选矿尾矿数量大量增加。尾矿资源的随意堆放不仅会消耗土地资源,而且会对周围环境造成一定的生态环境污染,同时伴随有很多潜在的安全隐患。植物修复技术作为尾矿治理以及尾矿库周围环境治理的一种绿色生态修复方法表现出很大的发展潜力,并被广泛应用。对尾矿污染现状、治理方法、植物修复技术的优势等作了详尽的阐述,分析了近几年来国内外的研究概况以及在尾矿治理和尾矿库环境治理中的应用现状,并对其存在的问题进行探讨。

The number of beneficiation tailings has went up significantly with the continuous development of the economy and the increasing scale of mining development recently.The random stacking of tailings resources not only consumes land resources, but also causes certain ecological environment pollution to the surrounding environment, accompanied by many potential safety hazards.Phytoremediation technology has shown great potential as a green ecological method for tailings treatment and environmental management around the tailings pond, and is in widespread use.In this paper, the status of tailings pollution, treatment methods, superior plant comparison, and advantages of phytoremediation technology are elaborated, analyzing the current research at home and abroad in recent years as well as the existing problems.
