摘要
基质的选择直接影响着潜流人工湿地全生命周期及污水处理效果,不同类型的基质对脱氮除磷具有差异性效果.综述了不同类型潜流人工湿地基质的研究现状,分析了其脱氮除磷机理,总结了各类基质的应用效果,展望了天然矿石基质、固体废弃物基质和人工合成基质研究方向和研究重点,以期为潜流人工湿地脱氮除磷基质的研发提供参考.
Abstract
The entire life cycle of a subsurface flow-constructed wetland and outcome of sewage treatment are directly impacted by substrate selection,different types of substrates show different performance on nitrogen and phosphorus removal.The research status of various types of subsurface flow constructed wetland was elabo-rated.the mechanism of it removing nitrogen and phosphorus were analyzed,and the application effects of differ-ent types of substrates were summarized.The research directions and focus of natural ore substrate,solid waste substrate and artificially synthesized substrate were prospected,which could provide reference for the research and development of substrates for nitrogen and phosphorus removal in subsurface flow constructed wetland.
