摘　　要：采用厌氧氨氧化反应器(ASBR)处理模拟生活污水,在温度为30℃时,控制进水NO_2^--N浓度为(30.0±0.2)mg·L^(-1),pH为(7.2±0.2),考察了NO_2^--N/NH_4^+-N分别为0.9、1.1、1.3、1.4、1.5和1.6时,对厌氧氨氧化(ANAMMOX)脱氮效果的影响.结果表明,当NO_2^--N/NH_4^+-N为1.4时,出水NH_4^+-N、NO_2^--N及TN的浓度分别为0.8、1.5和7.7 mg·L^(-1),NH_4^+-N、NO_2^--N及TN的去除率分别高达96.2%、95.4%和85.3%,此时脱氮性能最好,与发生厌氧氨氧化时NO_2^--N/NH_4^+-N理论值1.32比较接近.Anaerobic ammonia oxidation sequencing batch reactor（ ASBR） was used to treat simulated domestic waste water under the temperature of 30℃,the influent concentration of NO2--N of（ 30.0±0.2） mg·L-1,pH of（ 7.2±0.2） with the NO2--N/NH4＋-N were 0. 9,1. 1,1. 3,1. 4,1. 5 and 1. 6,respectively. Experimental results indicate that when the influent substrate ratio（ NO2--N/NH4＋-N） was 1.4,the effluent concentrations of NH4＋-N,NO2--N,TN were 0.8,1.5 and 7. 7 mg·L-1,respectively,the removal rates of them achieved to 96.2%,95.4% and 85.3%,respectively,and the highest removal rates of nitrogen were realized,which was closed to the theoretical value of 1.32 of the NO2--N/NH4＋-N of ANAMMOX.
