• 摘要：作者认为,高浓度泥水沉淀(浓缩)池的模型律,应建立在以下过程相似的基础上:(1)池内浑水异重流发生相似;(2)池内泥水的沉淀浓缩过程相似。文中讨论了原泥水或配制泥水进行试验、试验为正常负荷或超负荷、采用正态模型或变态模型等各种情况下的模型律以及不能满足相似条件的情况。文中介绍了在两个几何相似的模型中对模型律进行试验检验的结果。

• Abstract：The modeling law of sedimentation tank (or thickener) for concentrated turbid water has been contemplated on the basis of similarity to the. following processes: ( 1 ) density current in tank where buoyancy is assumed as the major interaction force; ( 2 ) settling-thickening process of turbid water in tank. In the case of normal load, similarity law is derivable depending on the law of settling-thickening process of turbid water in tank. In the case pf super load, in addition to above similarity to be met, similarity law of settling process between interface in tank should be considered.Various model laws were discussed for the cases of raw and synthetic turbid water, and for the cases of normal and super load, derived through the distorted and undistorred models.In the present paper results were introduced by a test on the modeling laws with two geometrically similar models.
