According to the problem that how to choose the installation position for sewage treatment mixer was uncertain, the flow field in the sewage treatment pool was simulated by the software FLUENT 6.3, using unstructured tetrahedral grid, moving coordinate system technology, k ∼ ε turbulence model and the SIMPLE algorithm. The distribution of velocity gradient in the whole pool was analyzed, and the flow field was compared at the different installation angles of sewage treatment mixer. The results show that the fluid flows along the axial direction of sewage treatment mixer, and diffuses along the radial direction. The stirring circulation is evident when the installation deviates from the narrow side, and the flow velocity of the whole pool is relatively uniform and greater than 0.3m/s. It is consistent with their work requirements, which not only improves the efficiency, but also saves costs.
