The long start-up time of the completely autotrophic nitrogen removal over nitrite (CANON) process is one of the main disadvantages of this system. In this paper, the CANON process with a submerged aerated biological filter (SABF) was rapidly started up within 26 days. It gave an average ammonium nitrogen removal rate (ANR) and a total nitrogen removal rate (TNR) of 94.2% and 81.3%, respectively. The phyla Proteobacteria and Planctomycetes were confirmed as the ammonia oxidizing bacteria (AOB) and anaerobic ammonium oxidation bacteria (AnAOB). The genus Candidatus Brocadia was the major contributor of nitrogen removal. pH and temperature affect the performance of the CANON process. This experimental results showed that the optimum pH and temperature were 8.0 and 30 °C, respectively, which gave the highest average ANR and TNR values of 94.6% and 85.1%, respectively. This research could promote the nitrogen removal ability of CANON process in the future.

该系统的主要缺点之一是亚硝酸盐（CANON）工艺完全自养脱氮的启动时间较长。在本文中，采用水下曝气生物滤池（SABF）的CANON工艺在26天内迅速启动。它的平均铵态氮去除率（ANR）和总氮去除率（TNR）分别为94.2％和81.3％。门菌属细菌和扁平菌被确认为氨氧化细菌（AOB）和厌氧铵氧化细菌（AnAOB）。念珠菌属是脱氮的主要贡献者。pH和温度会影响CANON工艺的性能。实验结果表明，最佳pH和温度分别为8.0和30°C，最高平均ANR和TNR值分别为94.6％和85.1％。这项研究可以在未来提高CANON工艺的脱氮能力。
