摘　　要：采用实验研究与理论分析相结合的方法,对A-O1-O2生物膜系统的SND(同时硝化反硝化)性能及其影响因素进行研究,对系统各部分SND的脱氮机理作了具体分析。结果表明,在控制O1池曝气量为14.2m3/h·m3,当O2池DO为2.8mg/L(曝气量3.8m3/h·m3)、ORP为117.5mV时,O2池与系统的TN去除率分别达到最大值43.3%和60.6%,此时系统的SND脱氮效果最好。The characteristic and influencing factors of SND in the A-O1-O2biofllm system were studied. The mechanism of nitrogen removal by SND in this system was analyzed. Results showed that when air supply in O1 was 14.2 m^3/h·m^3, DO in O2 was 2.8mg/L（air supply 3.8m^3/h ·m^3, ORP in O2 was 117.5mV, the maximum TN removal rate of 43.3% and 60.6% was observed in O2 tank and the system respectively. At this time, SND had the best perfosmance for nitrogen removal.
