    • 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.
    • 本发明教导了混合曝气膜生物反应器,其包括生物反应罐; 设置在生物反应罐内的多个膜组件; 一种大孔曝气装置,包括第一曝气管; 多个具有多个大孔的大孔喷头,大孔喷头设置在第一曝气管上; 和第一气泵; 以及包括第二曝气管的微孔曝气装置; 具有多个微孔的多个微孔头,所述微孔头设置在所述第二曝气管上; 和第二气泵; 其中所述第一曝气管连接到所述第一气泵; 第二通气管连接到第二气泵; 大孔头设置在膜组件下方; 微孔头设置在生物反应罐底部附近; 并且微孔的直径比大孔小。 根据本发明,通过两种通气类型,大孔曝气和微孔曝气,以相同的通气速率组合,膜生物反应器的氧气利用率增加,因此用于处理废水的能量消耗降低。 因此,反应器适用于处理高负荷有机废水。
