【摘要】 植物修复技术被广泛应用于污水生态系统的修复.污水植物修复技术的机理主要有植物提取、植物固定、植物挥发、根际过滤和植物转化.目前在污水前处理技术、超富集植物选育、工程实践、超富集植物的安全处理等方面都进行了广泛的研究.在今后的污水植物修复技术研究中应注意三方面的问题:植物的地域适应性,防止生物入侵,兼顾经济效益和生态效益.更多还原

【Abstract】 Phytoremediation technology was widely used in sewage ecosystem restoration.The major phytoremediation processes or technologies arephytoextaction,phytostabilization,phytovolatilization,rhizofiltration and phytodegradation. At present some research have carried out in the sewage pretreatment technology,hyperaccumulator breeding, engineering practice,safe handling of hyperaccumulators and other aspects.In the future,the wastewater phytoremediation research should pay attention to the following three aspects:plant geographical adaptability,biological invasions,the economic and ecological benefits.更多还原
