摘　　要：超累积植物修复重金属污染土壤具有能耗低、污染少的特点,修复过程中产生的大量含有害物质的植物组织的处置一直是人们关注的热点,资源化是其处置方向之一。基于大量国内外研究文献,阐述了超累积植物的资源化方法,包括焚烧、堆肥、高温分解、液相萃取、水热液化的原理及各种方法的优缺点,最后提出今后超累积植物产后资源化研究的方向。Phytoremediation of heavy metal contaminated soil with hyperaccumulators has the characteristics of low energy consumption and less pollution.The disposal of a large number of plant tissues containing harmful substances produced in the remediation process has always been a hot topic.Resource utilization is one of the disposal directions.Based on a large number of domestic and foreign research literature,this paper expounds the principles of resource utilization methods of hyperaccumulators such as incineration,composting,high temperature decomposition,liquid phase extraction,hydrothermal liquefaction.It is also analyzed that the advantages and disadvantages of various methods.Finally the direction of resource utilization of hyperaccumulators in the future was pointed out.
