摘　　要：为进一步提高实验效率并提升复合沉淀池的处理效能,利用Solidworks软件对沉淀池进行二维建模,将建好的模型导入计算流体力学软件Fluent,并对不同工况下的沉淀池运行状况进行数值模拟。研究结果表明:当挡板深度为2 m时,复合沉淀池沉淀区域的流速最小,沉淀效能最好;基于Fluent软件的数值模拟模型可较好地完成沉淀池模拟实验。In order to further improve the experimental efficiency and enhance the treatment efficiency of the composite sedimentation tank,two-dimensional modeling of the sedimentation tank is carried out using Solidworks software,and the built model is imported into the computational fluid dynamics software Fluent,and numerical simulation of the sedimentation tank operation under different operating conditions is carried out.The results show that the sedimentation zone of the composite sedimentation tank has the lowest flow rate and the best sedimentation efficiency when the baffle depth is 2m;the numerical simulation model based on the Fluent software can better complete the sedimentation tank simulation experiment.
