摘要
试验结果和理论分析表明,在原水水质、药剂种类及药剂投加量确定的情况下,Gt因素并不能完全反映水力条件对絮凝效果的影响。通过对影响絮凝效果的主要特征量进行分析,找出了描述特征量之间相互关系的准数方程的一般式:η=f(d/l,Re,ρ_s/ρ_w,C_o,Gt)。
The theoretical analysis and the test results show that the factor of Gt (velocity
gradient and time) doesn't reflect comprehensivly the influence of hydraulic condition on
flocculation effect in the definite condition of the waste water nature, the sort of coagulant
and its amount. The main characteristic physical variables of flocculation process are ana-
lyzed theoretically in this paper. The interrelationship between the variables is illustrated by
a function of dimensionless groupings as below:η=f(d/l, Re, ρ_s/ρ_w, C_0, Gt).
