重金属污染土壤植物联合修复技术研究进展

植物修复重金属污染的土壤是近几年发展起来的一项新的土壤污染治理技术,由于其环境扰动小、成本低廉等而被广泛应用.然而对于复杂的环境而言,单一的植物修复措施往往显得势单力薄,因此有必要针对环境中的具体污染状况,开展植物联合修复,提高修复效率,降低修复成本.简要论述了重金属污染土壤植物联合修复,重点阐述了近年来国内外利用植物联合修复技术在重金属污染土壤方面的研究进展,并对该领域的未来研究方向进行展望.

Research progress of phytoremediation combination technology to remediate heavy metal contaminated soil

Phytoremediation of heavy metal contaminated soil is a new treatment technology for soil pollution developed in recent years, due to the low cost and small environmental perturbations. For complex environments, however, phytoremediation of the single usually seems so weak, therefore it needs phytoremediation to improve the efficiency of remediation, reduce remediation cost. According to the existing research, this article briefly discussed the single phytoremediation of soil contaminated by heavy metals, focused on the research progress using phytoremediation combination technology in terms of heavy metals soil contaminated in recent years, in the mean time, the view also gave a prospection on the future research of the domain.
