【摘要】 在序批式活性污泥法反应器（SBR）中,采用全程自养脱氮（CANON）工艺,先以反硝化污泥为接种污泥,采用低基质含量配水通过逐步降低进水C/N及水力停留时间的策略快速富集厌氧氨氧化菌（anammox）,之后在低曝气条件下进一步缩短HRT以模拟生活污水富集氨氧化细菌（AOB）,基于对反应器内脱氮性能和不同阶段功能菌动力学活性的分析,系统阐述了功能菌演化的关键因素。结果表明,CANON工艺在75 d内成功启动,反应器氨氮去除率超过了93%;将该工艺应用于生活污水的处理,实现了高效的脱氮性能,反应器内anammox对NH₄⁺-N降解速率μ（NH₄⁺-N）与异养菌对COD的降解速率μ（COD）的比大于1.0,与反硝化菌的NO₃^--N降解速率μ（NO₃^--N）)比大于2.0。更多还原

【Abstract】 The experiment inoculated with heterogeneous denitrification biomass to rapidly enrich the anammox bacteria（ANAMMOX）in the sequencing batch reactor（SBR）,by CANON process,using the low concentration of artificial water distribution as influent water and simultaneously controlling the C/N loading rate and hydraulic retention time（HRT）.Then HRT was further shortened to simulate the enrichment of ammonia-oxidizing bacteria（AOB）.Based on the analysis of the performance of nitrogen removal and dynamics activities of functional bacteria in different stages,the main factors for the conversion of functional bacteria were stated.The results showed that,CANON process started successfully within 75 d,and ammonium-nitrogen removal rate exceeded 93%.This process was applied to the treatment of domestic sewage,and high efficient nitrogen removal performance was achieved.The ratio of NH₄⁺-N degradation rate（μ（NH₄⁺-N））by anammox to COD degradation rate（μ（COD））by heterotrophic bacteria and to NO₃^--N degradation rate（μ（NO₃^--N））by denitrification bacteria were greater than 1.0 and 2.0,respectively（μ（NH₄⁺-N）/μ（COD）>1.0,μ（NH₄⁺-N）/μ（NO₃^--N）>2.0）.更多还原
