摘　　要：利用计算流体力学对氧化沟的倒伞曝气机及推流器建立叶轮机械驱动模型,建立氧化沟污水-污泥多相流模型,利用计算流体力学软件Fluent对倒伞曝气机及推流器驱动的氧化沟进行流场模拟,能够较为准确的预判各种情况下的流场,有效地整合表面曝气机与潜水推流器的统一,能够很好地对氧化沟工程设计,设备配置及布置等起优化作用,并对污水厂运营起指导作用。Based on the computational fluid dynamics, the impeller drive model of inverted umbrella aerator and impeller of oxidation ditch and the wastewater-sludge muhiphase flow model of oxidation ditch were set up. Using Fluent, a softwater for computational fluid dynamics, to simulate the oxidation ditch drived by inverted umbrellar aerators and impellers can not only forecaste the flow field under different conditions exactly, gather the surface aerator and the submersible water impeller effectively, but also optimize the design of oxidation ditch and the device assignment and disposition evidently, supervise the operation of wastewater treatment plant as well.
