摘　　要：曝气池的设计及运行是影响活性污泥过程工作效率的主要因素之一。运用FLUENT软件对曝气装置为穿孔管的曝气池内气液两相流动进行了三维数值模拟,对比了相同曝气量条件下不同数量孔眼下的曝气效率,在本文所模拟的工况下采用四孔穿孔管曝气时曝气效率最高。Aeration tank design and operation are one of the main factors of effect of activated sludge process efficiency, gas-liquid two-phase flow in aeration with the perforated pipe was three-dimensional numerical sim-ulated by using FLUENT software. The aeration efficiency in same aeration quantity and different perforation number were contrasted using four holes perforated pipe aeration which had the highest efficiency in the simu-lated conditions.
