| 摘 要： | 在温度为30℃±1℃条件下,采用陶粒为填料的序批式CANON反应器,以人工配置无机高氨氮废水为进水,研究不同初始pH值对CANON工艺脱氮效果和N_2O释放的影响.试验过程中,控制进水氨氮浓度相同,HRT=5 h,曝气量为6m3·(m~3·h)~(-1)时,调节进水pH值分别为6.64、6.98、7.15、7.88和7.95,研究发现,初始pH值在6.64~7.95之间时,CANON工艺脱氮效果基本保持稳定,TN去除率分别为81.38%、87.32%、92.12%、88.21%和86.84%,TN去除负荷均在1.56kg·(m3·d)-1以上;各周期初始N_2O释放速率基本相同,先升高后降低,且初始pH值越低N_2O释放速率峰值越高,而N_2O释放量和释放率也均随初始pH增加而减少.初始pH值在6.64~7.95之间对总氮去除影响不大,但对N_2O释放有较大影响.要同步实现CANON工艺高效脱氮和N_2O释放减量化,应将进水pH调节在7.90附近.
