中文摘要:

建立了平流式沉淀池水流的两相流模型,应用计算流体力学软件Fluent求解模型。结果表明二沉池内水流速度是非均匀的；证明了悬浮物粒径对二沉池水流和悬浮物流速分布无明显影响,对实际污水厂处理有一定的指导意义。

英文摘要:

The paper built a two-phase flow model in rectangular secondary sedimentation tanks and resolved the model by use of the computational fluid dynamics software Fluent. The results showed that the distribution of flow velocity is not uniform, and MLSS diameter has no effect on the distribution of flow velocity of MLSS. It has some guidance for wastewater treatment.
