Abstract: This paper reviews the state of current research on endogenous sulfur intervening in anaerobic ammonium oxidation as well as possible coupled microbial processes. Future research should focus on the role of new-type autotrophic anaerobic ammonium oxidation in nitrogen-cycling processes in urban rivers, including sulfur-driven autotrophic partial denitrification with anaerobic ammonium oxidation, sulfate-type anaerobic ammonium oxidation, and ferric iron reduction coupled with anaerobic ammonium oxidation; in addition, future research should explore the role of endogenous sulfur in intervening in anaerobic ammonium oxidation and their coupled progress in treating urban rivers with a high level of nitrogen and a low C/N ratio. This is of great significance for solving the issue of high nitrogen levels in treating polluted urban rivers as well as improving our understanding of microbial processes of N-and S-cycling in aquatic environments.

Key words: urban river, endogenous sulfur, anaerobic ammonium oxidation, nitrogen removal
