| Abstract: |
| High nitrogen concentration in water can lead to eutrophication. New biological nitrogen removal technologies employ various coupling methods and can be used for different ammonia nitrogen concentrations, making them highly promising potential treatment candidates in the field of water nitrogen pollution treatment. Herein, the reaction pathways, research progress, and advantages and disadvantages of these new biological nitrogen removal technologies were systematically introduced. Moreover, the mechanism of biological denitrification in different reaction pathways, enzyme activity measurement, and the research status of biological denitrification were systematically described as well. Finally, the biological denitrification in new biological pathways was summarized, and the future prospects of biological denitrification were proposed. This review aims to enhance the efficiency of new biological nitrogen removal technologies in water nitrogen treatment and provide a theoretical basis and data support for research related to biological denitrification. |
