Anaerobic ammonium oxidation (anammox) is an environmentally sustainable process with high nitrogen removal efficiency; however, nitrite serves as the limiting factor in this process. Sulfur autotrophic denitrification (SADN) employs sulfide as an electron donor to reduce nitrate to nitrite. Therefore, coupling SADN and anammox (SDA) can improve the nitrogen removal efficiency. This review analyzes the coupling mechanisms of three common SDA systems: S-SDA, S-SDA, and SO-SDA, as well as the dominant genera in the SDA process. This paper summarizes the influence of key operating parameters, including influent nitrogen loading, pH, and the N/S ratio, on the nitrogen removal efficiency of the SDA process and the effect of SO addition on microbial structure in anammox. The application of the SDA process in real wastewater treatment is analyzed in detail. Overall, this overview of the SDA process plays an important role in the direction of the SDA development.
厌氧氨氧化是一种环境可持续且脱氮效率高的过程；然而，亚硝酸盐是该过程中的限制因素。硫自养反硝化利用硫化物作为电子供体将硝酸盐还原为亚硝酸盐。因此，将硫自养反硝化与厌氧氨氧化耦合（SDA）可以提高脱氮效率。本综述分析了三种常见SDA系统：S-SDA、S-SDA和SO-SDA的耦合机制，以及SDA过程中的优势菌属。本文总结了进水氮负荷、pH值和N/S比等关键运行参数对SDA过程脱氮效率的影响以及添加SO对厌氧氨氧化中微生物结构的影响。详细分析了SDA过程在实际污水处理中的应用。总体而言，对SDA过程的这一概述在SDA发展方向上发挥着重要作用。
