| Abstract: | The completely autotrophic biological nitrogen removal process possessed many advantages,such as less organic carbon demand, low energy-consumption, less land demand and simple operation. And it is regarded as an important research object in wastewater treatment. Therefore, this study summarized the mechanism and influencing factors of the completely autotrophic biological nitrogen removal process. The effects on nitrogen removal were analyzed, for example, temperature, pH, dissolved oxygen (DO), matrix concentration and other factors. This study could be used fora reference for the optimization of the completely autotrophic biological nitrogen removal process. |
