- Abstract:
- The start-up and operation of the completely autotrophic nitrogen removal over nitrite (CANON) process is facing significant challenges due to its stringent environmental requirements and difficulty in achieving efficient nitrogen removal. In comparison to the real-time control and other strategies, starvation regulation offers several advantages, including ease of operation, reduced operating costs, improved short-cut nitrification, and enhanced resilience against adverse conditions like substrate shortage and low temperature shocks. Current research on starvation regulation of CANON process primarily focuses on the analysis of the decay rate of nitrifying bacteria and the effect of environmental factors on Anammox. However, there are gaps in current dynamic studies, as well as a lack of understanding regarding the interaction of multiple factors within the CANON process and the absence of mathematical models for predicting their effects. Based on this, this paper summarized the effects of starvation regulation on nitrification system and Anammox, as well as the characteristics of starvation regulation and the restoration of the damaged system. This research paves the way for further research on the rapid start-up and stable operation of CANON process.
