摘　　要：介绍了采用上流式厌氧生物膜反应器耦合二级生物接触氧化处理猪场废水。在一级生物接触氧化池内实现短程硝化,将产生的NO2-回流至上流式厌氧生物膜反应器,在上流式厌氧生物膜反应器内实现厌氧氨氧化与反硝化协同,实现在厌氧条件下对NH4+-N的去除。将该系统用于处理实际猪场废水,系统对猪场原废水COD平均去除率为97%,TN平均去除率为84.2%,NH4+-N平均去除率分别为88.2%。The article proposed a new up-flow anaerobic sludge bed and biofilm（UASBB） coupled with two-stage biological contact oxidation process. NO2-produced in the first stage contact oxidation was reflux into the UASBB. There was a lot of obviously synergy between anaerobic ammonium oxidation and denitrification in UASBB, achieving ammonia nitrogen removal under anaerobic condition. The coupling system was applied in the actual swine wastewater treatment. For this system, the removal of COD rate was 97%, the removal of TN rate was 84.2%, the removal of ammonia nitrogen rate was88.2%
