采用SBBR反应器，接种普通污水厂剩余污泥，以人工配制含NH4+-N和NO2--N的低氨氮废水为进水， NH4+-N、NO2--N分别为24.3~32.0 mg/L、31.9~37.5 mg/L， pH为7.60~7.75，水温为（32±1）℃，考察低基质条件下厌氧氨氧化反应器启动及稳定运行特征。结果表明：经100余天后，SBBR厌氧氨氧化反应器成功启动。进水TN为60.8~68.7 mg/L时，平均去除率为88.3%，NH4+-N和NO2--N的去除率均达到95%以上。稳定运行期间，NH4+-N去除量、NO2--N去除量和NO3--N生成量的质量浓度之比为1∶1.37∶0.27，出水pH略高于进水，稳定在7.95左右。

The start-up and characteristics of stably running anaerobic ammonium oxidation (anammox) under low substrate conditions has been investigated,using SBBR and inoculated excess sludge from an ordinary sewage treatment plant,and artificially prepared low ammonia-nitrogen wastewater consisting of NH4+-N and NO2--N as influent,when the mass concentrations of NH4+-N and NO2--N are 24.3-32.0 mg/L and 31.9-37.5 mg/L,respectively, pH 7.60-7.75 and temperature of the influent (32 ±1) ℃. The results show that the SBBR can be started up successfully,after 100 days or more. And,when the mass concentration of influent TN is 60.8-68.7 mg/L,the ave-rage removing rate is 88.3%,and the removing rates of both NH4+-N and NO2--N can reach 95%above. The mass concentration of NH4+-N removing rate,NO2--N removing rate,and NO3--N production quantity is 1∶1.37∶0.27. The effluent pH is stable,at about 7.95,which is a little higher than that of influent.
