摘要

摘要: 潜流人工湿地具有操作简单,建设和运行成本低,环境效益好等优点,但在长期运行过程中普遍存在脱氮效率降低的问题。阐述了潜流人工湿地脱氮机理,提出湿地复氧能力降低和基质堵塞是造成人工湿地长期运行脱氮效率降低的主要原因。基于文献分析,综述了潜流人工湿地长期运行提高脱氮效率的方法,分别从提高湿地复氧能力,选择合适的基质粒径和级配及优化潜流人工湿地工艺等方面阐述了提高脱氮效率的措施及其效果。

Abstract: Subsurface flow constructed wetlands have the advantages of simple operation, low cost of construction and operation, and good environmental benefits. However, in the long-term operation, the phenomenon of low denitrification efficiency is also common. The mechanism of denitrification in subsurface flow constructed wetland was stated and the main reasons for the decrease of denitrification efficiency in long-term operation were reoxygenation capacity reduction and substrate clogging. Based on extensive literature review, the methods of improving denitrification efficiency by long-term operation of subsurface flow constructed wetlands were summarized. The measures and effects for improving denitrification efficiency were discussed from the aspects of improving reoxygenation capacity of wetland, selecting suitable filler size and gradation, and optimizing subsurface flow wetland process.
