【摘要】：絮凝构筑物设计阶段普遍使用基于层流理论的甘布公式计算平均G值,对絮凝池内部细节设计缺乏紊流理论依据。为此,依据紊流理论,基于群体平衡原理,建立了完整的絮凝反应模型(Floc-SMEDI)。通过非定常湍流模型、多相流模型、群体平衡模型以及絮凝反应模型的耦合,模拟水处理絮凝阶段絮体的变化过程。经过多种池型的测试,该模型能有效模拟絮凝过程中絮体的变化情况,为絮凝池的优化设计以及新池型的研发提供了新依据。
[Abstract]:In the stage of flocculating structure design, the Gambun formula based on laminar flow theory is widely used to calculate the average G value, which is lack of turbulence theory basis for the detailed design of the flocculation tank. Based on the turbulence theory and the principle of population equilibrium, a complete flocculation reaction model, Floc-SMEDIA, was established. Through the coupling of unsteady turbulence model, multiphase flow model, population equilibrium model and flocculation reaction model, the variation process of flocs in flocculation stage of water treatment was simulated. The model can effectively simulate the variation of flocs during flocculation and provide a new basis for the optimization design of flocculating tank and the research and development of new type of flocculation pool.
