摘要:
全程自养脱氮（CANON）工艺的启动和运行对环境要求高，相比于实时控制等策略，饥饿调控易于操作，能够减少运行费用，提高短程硝化效果，增强应对底物不足及低温冲击等不利因素的能力。目前，关于饥饿调控CANON工艺的研究主要集中在硝化细菌衰减速率的分析以及环境因素对厌氧氨氧化的作用等方面。但是，当前该领域的动力学研究存在不足，针对多种因素共同作用于CANON工艺的研究存在空白，也缺乏用于预测影响结果的数学模型。基于此，分别总结了饥饿调控对硝化系统和厌氧氨氧化的影响，以及饥饿调控的特点和对受破坏系统的恢复情况，以期为后续开展CANON工艺的快速启动和稳定运行的相关研究提供新的探索途径。
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.
