摘要
气泡与絮粒的粘附是气浮净水中至关重要的一个阶段。本文从“分离压”的基本原理出发,通过气泡-絮拉间残留水化层性能的测定计算,探讨了气泡与絮粒粘附时液膜薄化的物理因素和化学因素。借助高速摄影,结合统计分析,研究了气泡-絮粒粘附过程的机理,得出了几点有关信息。
The attachment of bubble-floc is a crucial step on dissolved air flotationin water purification.This paper,according to the basic principle of disjo-ining pressure and determination of residual liquid film between the bubbleand the floc,deals with physical aspects of thining of intervening liquidfilm and chemical parameters used to control bubble-floc attachment.With the help of high photograph and statistical analysis,the mechanismof bubble-floc attachment has been studied and some information on bubble-floc attachment has been attained.
