摘要：

Partial denitritation Anammox (PD/A) process has been regarded as a novel biological nitrogen removal process with the most mainstream engineering application prospects in recent years due to its advantages of no aeration, less waste matter yield and less demand for organic carbon sources. Firstly, this paper expounds the principle and characteristics of PD/A process. Then, the paper summarizes the key factors affecting PD/A process from the aspects of pH, carbon source, salinity and heavy metals. Meanwhile, the control strategies of realizing rapid enrichment and good coordination of core functional flora in PD/A process are put forward. Then, a variety of derivative processes developed from PD/A process are summarized, and the research prospects of these derivative processes are analyzed from the aspects of process stability, economy and controllability. Finally, the research focus of PD/A process in the future is prospected, that is, the use of metagenomic technology to identify the resistance formation mechanism of PD/A process under adverse habitat stress is beneficial to the practical engineering application of mainstream Anammox process in the future. What’s more, it is believed that coupling with the existing mature biological denitrification process under the background of carbon peaking and carbon neutrality to realize the economical, efficient and standard treatment of various wastewaters will be a key research direction of PD/A process in the future. © 2023 Chemical Industry Press.
