摘　　要：在A/O工艺系统中组合膜生物反应器(MBR)处理养猪污水,研究混合液污泥质量浓度(MLSS)、氨氮负荷(AL)、碱度、DO与HRT等因素对脱氮的影响.结果表明,通过MBR系统提升MLSS,可提高A/O工艺的脱氮效果,并可减少反应HRT及DO与碱度的消耗.Through the system which combined A/O process with MBR to treat pig sewage, the factors of denitrogenation were studied as MLSS, AL, alkalinity, DO, HRT and so on. The results showed that the system can improve A/O denitrogenation process and reduce HRT and the consumption of DO and alkalinity through the enhancement MLSS by MBR.
