| 中文摘要 |
| 氮素化合物作为水体重要污染物之一，其过量排放对生态环境与人体健康造成了重大影响，因此对污水中氮素化合物的关注和控制尤为重要. 人工湿地（CWs）作为一种灵活、高效的废水处理系统，在氮循环过程中扮演着至关重要的角色. 基质是CWs的重要组成部分，其种类与CWs脱氮性能密切相关. 在此背景下，通过引入生物炭和天然矿物充当CWs基质，综述了两者填充方式、填充数量和粒径大小等特性参数对CWs整体脱氮性能的影响. 其次，深入探究了两者对CWs中硝化、反硝化和厌氧氨氧化（ANAMMOX）等关键脱氮环节的影响，明晰两者促进CWs整体脱氮性能的作用机制. 最后，从经济和环境角度讨论了两者的填充方式给CWs脱氮处理带来的问题并给出了优化建议. 研究结果可为CWs构建提供合理依据，确保其有效性和长期可持续性. |
| 英文摘要 |
| Nitrogen compounds， as one of the important pollutants in water bodies， have caused significant impacts on the ecological environment and human health because of their excessive discharge. Therefore， it is particularly important to pay attention to controlling nitrogen compounds in wastewater. Constructed wetlands （CWs）， as a flexible and efficient wastewater treatment system， play a crucial role in the nitrogen cycling process. Substrate is an important component of CWs， and the selection of its species is closely related to the nitrogen removal performance of CWs. In this context， biochar and natural minerals were introduced as substrates for nitrogen removal process of CWs. The impacts of characteristic parameters of biochar and natural minerals， such as filling method， filling quantity， and particle size， on the overall nitrogen removal performance of CWs were reviewed. Furthermore， the effects of both on the key nitrogen removal processes， such as nitrification， denitrification and anaerobic ammonia oxidation （ANAMMOX） in CWs were investigated in depth， and the mechanisms by which both promote the overall nitrogen removal processes of CWs were clarified. Finally， the problems of both in filling CWs from economic and environmental perspectives were discussed and optimization suggestions were given. The research can provide rational basis for the construction of CWs， ensuring their effectiveness and long-term sustainability. |
