修复植物产后处置技术现状与展望

TECHNIQUES FOR DISPOSAL OR REUSE OF PHYTOREMEDIATING PLANTS─PRESENT AND FUTURE

针对修复植物的类型、特点、应用潜力探讨了修复植物的处置方法,如焚烧法、压缩填埋法、堆肥法等,有的还可使超积累植物残体得到回收利用,避免其对环境造成“二次污染”。同时指出了目前修复植物处置存在的问题及今后应重视的研究方向,以期为修复植物的资源化综合利用提供途径与方法,为植物修复应用和推广奠定技术基础。

Methods for disposing hyperaccumulators, such as incinerating, compressing for land filling, composting, etc. were summarized, and potentials to recycle the plants as resources while avoid ＂secondary pollution＂ of the environment were also discussed in this paper. Meanwhile, the authors also mentioned existing problems and concerns that called for more attention in future studies in the hope that better approaches and methods could be found to recycle phytoremediating plants as resources, thus laying down a sound technical foundation for application and extension of the phytoremediation technology.
