摘　　要：以片状海绵作为CANON反应器的填料,通过接种CANON污泥,采用人工配制高氨氮废水为进水,研究了水力停留时间(HRT)对生物膜CANON反应器去除TN及短程硝化的影响。控制反应器的HRT分别为5、7、9 h,研究发现:当HRT=5 h时系统的短程硝化稳定性能较佳,但对TN的去除率、去除负荷分别只有32.02%、0.689 kg/(m3·d);当HRT=7 h时,反应器的短程硝化稳定性能较佳,且对TN的去除率、去除负荷分别可达58.05%、0.863 kg/(m3·d);当HRT=9 h时,反应器对TN的去除率、去除负荷分别为73.96%、0.854 kg/(m3·d),但短程硝化稳定性能不佳。对于片状海绵填料反应器而言,HRT越短则短程硝化效果越稳定。Sheet sponge was used as the carrier in CANON reactor, and the effect of different hydraulic retention times on the performance of CANON reactor was investigated by seeding sludge from an- other mature CANON reactor and using synthetic inorganic ammonia-rich wastewater as the infiuent. The hydraulic retention times were controlled at 5 h, 7 h and 9 h respectively. The results showed that （1） when hydraulic retention time was 5 h, the performance of nitritation was stable, but total nitrogen removal rate was only 32.02% with removal load of 0.689 kg/（ m3 . d） ; （2） when hydraulic retention time was 7 h, the performance of nitritation was stable, and total nitrogen removal rate was up to 58.05% with removal load of 0.863 kg/（ m3 . d） ; and （3） when hydraulic retention time was 9 h , the performance of nitritation was unstable, but total nitrogen removal rate was up to 73.96% with removal load of 0. 854 kg/（m3 . d）. For the sheet sponge reactor, the shorter the HRT was, the more stable the nitritation could be.
