| 摘 要： | 膜生物反应器（MBR）中，在DO为1mg/L左右，MLSS为8000-9000mg/L，温度为24℃，进水pH值为7.2，COD、NH3-N分别为523-700mg/L和17.24-24mg/L的相对稳定条件下，对COD、NH3-N、TN的去除率分别为96%、95%、92%。详细分析了在控制DO的条件下，MBR发生同步硝化、反硝化的原因，并提出了在单级好氧反应器中控制DO可发生短程硝化一反硝化生物脱氮的机制。

| Abstract: | In the membrane bioreactor,under the relative stable conditions of DO 1 mg/L,MLSS 8 000 ～ 9 000 mg/L,temperature 24 ℃,influent pH 7.2,COD 523 ～700 mg/L and NH4+17.24～24 mg/L,96%,95%,and 92% are achieved respectively for the removal of COD,NH4+,and TN.The reason of simultaneous nitrification and denitrification occurring in MBR under controlled DO is described in details.The mechanism that shortcut nitrification and denitrification may occur under controlled DO in a single-stage aerobic reactor is also presented. |
