摘要

人工湿地中最重要的脱氮过程是硝化和反硝化。这些过程在19世纪下半叶得到了很好的描述，现在仍然有效。近年来，人们还发现了其他一些处理生化水脱氮的方法，如厌氧氨氧化（Anammox）、厌氧氨氧化-偶联异化铁还原（Feammox）和自养反硝化。此外，还发现了可以将氨完全氧化为硝酸盐的细菌（Comammox）。本文主要针对这些新发现的与化粪池废水处理有关的工艺进行综述。

Nitrogen removal in constructed wetlands

The most important processes responsible for nitrogen removal in constructed wetlands (CWs) are nitrification and denitrification. These processes were well-described in the second part of the 19th century and are still valid. During the recent years, other processes responsible for nitrogen removal in CWs have been identified, namely anaerobic ammonia oxidation (Anammox), anaerobic ammonia-oxidation-coupled-to-dissimilatory ferric iron reduction (Feammox) and autotrophic denitrification. Also, bacteria that can perform complete oxidation of ammonia to nitrate (Comammox) have been discovered. This review is mostly aimed at these newly discovered processes in relation to wastewater treatment in CWs.
