采用分段投料的改良单级潮汐流人工湿地（TFCW），通过亚硝酸盐完全自养脱氮（CANON）工艺实现高速率脱氮，并在分流比约束条件下探讨TFCW处理生活污水的氮转化途径.分流比显着影响氮转化途径在整个实验中的TFCWs。当分流比为1：1时，厌氧氨氧化菌富集效果最好，然后在适当的限氧条件下，启动CANON工艺。TN平均去除率为（127.00 ± 13.78）mg（L d）− 1。研究表明，适宜的分流比有利于CANON工艺在TFCW内的自养脱氮，并优化了TFCW内的微环境。TFCW脱氮的最佳分流比为1：1。
This study attempts to achieve a high-rate nitrogen removal via the complete autotrophic nitrogen removal over nitrite (CANON) process in a modified single-stage tidal flow constructed wetland (TFCW) with step-feeding, and nitrogen transformation pathways in the TFCWs treating domestic wastewater were explored under shunt ratio constraints. Shunt ratio significantly affected nitrogen transformation pathways in the TFCWs throughout the experiment. The anammox bacteria were enriched most effectively at the shunt ratio of 1:1, and then the initiation of a CANON process was accomplished in the TFCW under the appropriate limited oxygen condition. The mean TN removal rate reached up to (127.00 ± 13.78) mg (L d)−1correspondingly. It could be concluded that autotrophic nitrogen removal via CANON process developed in the TFCW with optimized microenvironment that developed as a result of appropriate shunt ratio. The optimal shunt ratio of the TFCW for nitrogen removal was 1:1.
