| Summary: | Anaerobic ammonia oxidation (ANAMMOX) is an efficient and low-fare biological nitrogen removal process. Nevertheless, there are still some challenges in mainstream request due to the limitations of substrate type and nitrate accumulation. At the present, anaerobic ammox combined process has been widely studied to solve the above issue. In this paper, the anammox combined processes developed in recent years are reviewed, and the process principles, pros and cons, influencing factors, process scalability, key bottlenecks in application and relevant work of the investigation group are discussed. Finally, the evolution of complex anammox process in urban domestic wastewater treatment was prospected.
