城市污水处理厂污水经部分硝化反应器处理后，采用搅拌式厌氧氨氧化反应器进行处理。结果表明，进水NO2--N/NH4+-N比值的变化对反应器的性能有负面影响，尤其是在T-N浓度较高的情况下。进水总有机碳浓度大于50 mg/L对厌氧氨氧化反应器的脱氮效果有严重影响。扫描电子显微镜观察表明，厌氧氨氧化颗粒污泥的表面被一些物质覆盖，可能是部分硝化污水中含有的出水SS。此外，对厌氧氨氧化颗粒污泥的细菌组成的研究表明，即使在抑制阶段，厌氧氨氧化细菌也是优势菌Planctomycete KSU-1。
Reject water from a municipal wastewater treatment plant was treated using a stirred tank anammox reactor after being treated by a partial nitrification reactor. The results indicated the variations in the influent NO2--N to NH4+-N ratio had a negative effect on reactor performance, especially when the T–N concentrations were high. Influent total organic carbon concentrations greater than 50mg/L were proven to have a serious effect on the nitrogen removal efficiencies of the anammox reactor. Observations by scanning electron microscope showed that the surface of the anammox granular sludge was covered by some materials, possibly the effluent SS contained in the partial nitrified reject water. Furthermore, the study of the bacterial composition of the anammox granular sludge showed that the anammox bacterium, Planctomycete KSU-1, was dominant, even during the inhibition phase.
