摘　　要：采用SBR反应器对比研究了序批式生物膜-活性污泥复合反应器(HSBR)与活性污泥反应器(SBR)的碳氮去除。结果表明,两反应器在COD、NH_(4)-N去除率方面无明显差异,但HSBR的NH_(4)-N过程去除速率显著高于SBR反应器,且HSBR反应器的TN去除率可达62.95%,高于活性污泥反应器39.3%。HSBR的悬浮污泥和附着污泥的比硝化速率分别为2.14 mgNH_(4)-N/(gTS.h)和1.16 mg mgNH_(4)-N/(gTS.h),比反硝化速率分别为0.16 mgNO_(x)-N/(gTS.h)和1.22 mgNO_(x)-N/(gTS.h),显示HSBR的硝化作用主要集中在悬浮污泥中,而反硝化作用则主要是由生物膜附着污泥完成。The carbon and nitrogen removal was comparatively studied in hybrid sequencing batch reactor (HSBR) and sequencing batch reactro (SBR).Results showed that no obvious difference in COD and NH_(4)-N removal for the two reactors while NH_(4)-N process removal rate in HSBR was rapider than that SBR.Meanwhile,the TN removal efficiency of HSBR was 62.95%which was higher than that in SBR of 39.3%.The specific nitrification rate of suspended sludge and attached sludge in HSBR was 2.14 mgNH_(4)-N/(gTS.h) and 1.16mg mgNH_(4)-N/(gTS.h),and the specific denitrification rate of HSBR was 0.16 mgNO_(x)-N/(gTS.h) and1.22 mgNO_(x)-N/(gTS.h).It revealed that the nitrification was mainly finished in suspended sludge while denitrification was in attached sludge of biofilm.
