摘　　要：为解决传统AO工艺在处理高氮废水中耗能大、脱氮效果不佳的问题,先构建传统AO装置,对污水进行处理并分析其处理效果。随后于相同条件下,在该装置中加装膜曝气生物膜反应器(MABR)组件,再次运行并对比前后数据。结果显示,MABR+AO工艺在最佳运行参数下,系统运行稳定后COD Cr,NH_(4)^(+)-N和TN的去除率分别达到了93.75%,99.37%,74%,脱氮效果优于传统AO工艺。生物膜中的优势菌种为变形菌门。研究证明了MABR强化传统AO工艺处理高氮废水具有较好潜力。In order to solve the problems of high energy consumption and poor denitrification effect in the treatment of high-nitrogen wastewater by the traditional AO process,a traditional AO device was first constructed to treat the wastewater and analyze its treatment effect.Subsequently,under the same conditions,a membrane aerated biofilm reactor(MABR)component was installed in this device,and it was operated again and the data before and after were compared.Under the optimal operating parameters,the removal rates of COD Cr,NH_(4)^(+)-N and TN in the system reached 93.75%,99.37%and 74%respectively by MABR+AO process,and the denitrification effect was better than that of the traditional AO process.The dominant bacteria in the biofilm were Proteobacteria.It is proved that MABR enhanced traditional AO process has a good potential to treat high nitrogen wastewater.
