本文根据流体力学模型实验理论,对影响絮凝过程的主要特征量进行了分析,找出了描述特征量之间相互关系的准数方程的一般表达式以及它在通常条件下的简化形式,R_e,GT)=0模型试验结果证明了,R_e,GT 三个无因次变量均对絮凝过程产生重要影响,且在一定的尺寸条件下,准数方程呈下列具体化形式GTR_e~(-1/2)=B对于具有几何相似关系的絮凝池,在其它条件相同的情况下达到相同处理效果时,GTR_e~(-1/2)值为一常数,因而笔者建议以 GTR_e~(-1/2)作为絮凝池模型试验的相似准数。
Based on the theory of fluid mechanics model experiments, this paper analyzes the main characteristic quantities affecting the flocculation process, finds the general expressions of the quasi-number equation describing the relationship between feature quantities and its simplified form under normal conditions, R_e, GT) = 0 model test results prove that the three dimensionless variables of R_e and GT all have an important influence on the flocculation process. Under a certain size condition, the accuracy equation has the following specific form GTR_e~(-1/2). )=B For a flocculation cell with a geometric similarity relationship, GTR_e~(-1/2) is a constant when the same treatment effect is achieved under the same other conditions, so the author proposes to use GTR_e~(-1/2). Similarity criteria as the flocculation tank model test.
