摘要(Abstract)：

介绍了人工湿地脱氮处理工艺的研究现状,分别简述了短程硝化-反硝化、厌氧氨氧化、全程自养脱氮、硫自氧反硝化等4种生物脱氮途径的基本原理,分析了它们应用过程中的影响因素,并进一步比较了4种脱氮新途径的工艺特点、脱氮途径、启动运行情况以及优缺点;分析表明,通过生物脱氮新途径,可强化人工湿地的生物脱氮作用,同时也可以解决人工湿地脱氮处理技术所面临的技术难题。基于此,对人工湿地脱氮领域进行了展望:1)新型生物脱氮克服了传统生物脱氮存在的耗氧量大、碳源不足等问题,在未来人工湿地脱氮领域将有更广泛的应用;2)在脱氮过程中,将多种类型的生化反应结合起来,突破传统反应的局限,将成为人工湿地实现氮脱除的新思路;3)在今后的研究中,可以有针对性地对湿地内的脱氮微生物及其影响因子进行研究,还可将传统生物脱氮与新型生物脱氮途径相结合,应用于人工湿地系统。
