    摘要: The present invention teaches a hybrid aeration membrane bioreactor, comprising a bio-reaction tank; a plurality of membrane modules disposed within the bio-reaction tank; a macropore aeration apparatus comprising a first aeration pipe; a plurality of macropore heads having each a plurality of macropores, the macropore heads being disposed on the first aeration pipe; and a first gas pump; and a micropore aeration apparatus comprising a second aeration pipe; a plurality of micropore heads having each a plurality of micropores, the micropore heads being disposed on the second aeration pipe; and a second gas pump; wherein the first aeration pipe is connected to the first gas pump; the second aeration pipe is connected to the second gas pump; the macropore head is disposed below the membrane module; the micropore head is disposed near the bottom of the bio-reaction tank; and the micropores are smaller in diameter than the macropores. In accordance with the present invention, two aeration types, the macropore aeration and the micropore aeration, are combined, at the same aeration rate, the oxygen utilization rate of the membrane bioreactor is increased and thus the energy consumption for treating waste water is decreased. Therefore, the reactor is suitable for treating highly loaded organic waste water.
