| 摘 要： | 对往复隔板絮凝池内的流场进行了数值模拟 ,并根据絮凝池的工作特征分析了水流状态对混凝效果的影响。结果表明絮凝池转弯处过水断面面积A_1 与廊道过水断面面积A_2 的比值A =A_1 / A_2 ,这一影响流场紊流动能的设计参数的最佳范围是 1 2～ 1 5。按此设计参数设计的往复隔板絮凝池模型的混凝反应效率是比较理想的。

| Abstract: | In this paper, the numerical simulation is applied to the flow field for a reciprocating baffled flocculation tank.Based on the characteristic of flocculation tank an analysis of the influence of the flow field on flocculation is carried out.The conclusion indicates the optimum value of A 1/A 2 is from 1.2 to 1.5,where A 1 is the area of the wetted cross section in the corner and A 2 is the area of the wetted cross section in the gallery.The coagulation efficiency in the tank is relatively perfect if designed it according to the optimum value of A 1/A 2. |
