摘要
利用生态浮岛净化污染水体是一个处于原始状态的生态恢复过程,是一个复杂的物理化学和生物过程。其核心是水生植物及其根系微生物能够吸收氮、磷营养盐,降解水体中有机物和富集重金属离子。在国内外的一些水污染治理工程中应用了生态浮岛,并取得了一定的成效。影响污染物去除率的因素有植物品种、温度、季节、处理时间和初始浓度等。从植物及其组合、植物结构改造和水生资源利用等方面进行展望,并探讨了植物生态系统的建设和管理技术,以实现景观效益和生态功能的双赢。
Using Ecological floating island(EFI)topurify polluted water is a process of ecological restoration at virgin position,as well as a complicated physical,chemical and biological process.Its core is utilizing aquatic plants and root's microbes to absorb nitrogen and phosphorus elements,degrade organic matter and enrich heavy metal.EFI has been applied to some water pollution control projects at home and abroad,and has got several achievements.However,there are some factors influenced the removal rate of pollutants,including plants,temperature,seasons,processing time and initial concentration,the transformation of EFI structure and the utilization of aquatic resources,and probed the technology of EFI's building and management,to implement the win-win of landscape benefit and ecological restoration.
