摘　　要：氮作为污水中普遍存在的成分,是造成水体富营养化的主要因素之一。人工湿地技术是一种创新生态修复技术,不仅对维护水体生态平衡至关重要,还有助于实现污水的资源化利用。基质在人工湿地系统的脱氮过程中起着至关重要的作用。本研究综合评述分析了人工湿地的脱氮机制以及高效脱氮基质的关键特性,对目前人工湿地中应用的典型单一基质和组合基质的脱氮效果进行了系统总结,并展望了人工湿地高效基质筛选在强化脱氮作用方面的未来研究趋势和所面临的挑战。Nitrogen,as a common component in wastewater,is one of the main factors causing eutrophication.Constructed wetland technology is an innovative ecological restoration technology,which is not only crucial for maintaining the ecological balance of water bodies,but also helps to achieve the resource utilization of sewage.The substrate plays a crucial role in the denitrification process of artificial wetland systems.This study comprehensively reviews and analyzes the denitrification mechanism of constructed wetland and the key characteristics of efficient denitrification substrates.It systematically summarizes the denitrification effects of typical single and combined substrates used in constructed wetland,and looks forward to the future research trends and challenges of efficient substrate screening in enhancing denitrification in constructed wetland.
