| 摘 要： | 常温(25±1)℃下,向中置(R1)、底部曝气(R2)的AUSB反应器中接种絮状厌氧氨氧化(ANAMMOX)污泥,研究AUSB不同曝气位置对连续流CANON颗粒污泥工艺启动及运行的影响.结果表明,R1、R2分别于第43 d、56 d成功启动CANON颗粒污泥,平均粒径分别为214.79μm、205.27μm,特征值(ΔNO-3-N/ΔTN)为0.128、0.129.低氨氮(90 mg·L-1)下,逐步增大氮负荷(NLR),AUSB中置曝气更利于CANON颗粒粒径的持续增长及脱氮负荷(NRR)的提高,R1于第88 d颗粒平均粒径即增至507.46μm,NRR达0.277 kg·(m3·d)-1;R2污泥颗粒历时108 d,粒径增长至467.72μm,NRR仅为R1的87.73%.底部曝气AUSB全程好氧模式下长期运行,亚硝酸盐氧化菌(NOB)显著增殖,第125 d后特征值增至0.136±0.004,NRR仅(0.231±0.015)kg·(m3·d)-1;而中置曝气AUSB特定的缺氧/好氧模式有效抑制了NOB活性,特征值维持在0.127±0.003,NRR为(0.262±0.019)kg·(m3·d)-1.AUSB中置曝气可促进絮状ANAMMOX污泥演变至CANON颗粒污泥,且系统脱氮性能及运行稳定性均优于底部曝气AUSB.
