| 摘 要： | 曝气池是活性污泥处理系统中的核心处理构筑物,而曝气池中气液两相分布及其流动规律对曝气作用的影响又至关重要。本文运用FLUENT软件对曝气池内气液两相流动问题进行了数值模拟,并对比了相同的曝气量,不同的孔眼数量下,曝气池内气液两相的分布情况和流动规律,说明了在本文所模拟的工况下采用孔眼数量为五孔时曝气效率最高。

| Abstract: | Aeration tank is the core structure of activated sludge treatment system, the distribution and the rule of gas/liquid two-phase flow have great important effects on the aeration function. The paper used FLUENT to simulate the gas/liquid two-phase flow in aeration tanks, and contrasted the distribution and flowing regulation in the same amount of aeration and different number of aerators. The article indicated that the aeration had the most efficiency when the number of aerators was 5 in the simulated condition. |
