摘要
人工湿地污水处理系统作为一种生态处理工艺具有投资少、能耗低、运行成本低、缓冲容量大和处理效率高等优点,已逐渐被广泛采用。阐述了用于人工湿地污水处理的复合填料的研究进展,包括人工湿地污水处理系统的基本概念,人工湿地的净化机理,填料的选择、制备与应用,特别是在考虑降低人工湿地污水处理系统建设成本的基础上推出的新型高效人工湿地填料,为人工湿地的应用和推广提供了有价值的参考。
Constructed wetland＇s wastewater treatment system with some advantages such as lower investment, lower energy consumption, lower operation cost, bigger buffer capacity and higher processing efficiency has been widely used. This paper expounds the progress of the research on the composite fillers used in constructed wetland＇s wastewater treatment, including the basic concept of constructed wetland＇s wastewater treatment system, constructed wetland＇s purification mechanism, fillers, selection, production and application, spatially the new-type high-efficiency constructed wetland＇s fillers developed based on the consideration about reducing the construction cost of constructed wetland＇s wastewater treatment system, providing valuable reference for the application and popularization of constructed wetland.
