ABSTRACT:
On the basis of summarizing and analyzing the theory of coagu-flocculation and its practical application, this paper proposes a physical model for coagu-flocculation. The model defines the process of coagu-flocculation as three steps: mixing, coagulation and flocculation, though there is no strict distinction in the practical processes themselves. Through experiment, two facts are verified: (1) with organic flocculants mixing and flocculation occur substantially in the same step, and need strong mixing intensity; while with inorganic flocculants much weaker mixing intensity is needed; (2) so as to ensure big floccules are formed, weaker mixing for a certain period of time is required.
