摘　　要：介绍了分形理论基本要点,探讨了分形理论在混凝形态学和絮凝动力学中的应用,论述了在经典Smoluchowski方程基础上引入分形维数建立的聚合分形球体模型及其基本方程,探讨了水量、反应时间、搅拌速率、pH值、混凝剂投加量、助凝剂投加量对分形维数值的影响。This paper summarizes some conclusions of fractal theory, coagulation morphology and flocculation kinetics, expounds the coalesced probes into the application of fractal theory in fractal sphere model and some equations which are built on the basis of classical Smoluchowski equations, and probes into the influence the water quantity, reaction time, stir speed, pH value,and coagulant dosing amount on fractal dimension.

关 键 词：分形理论 分形维数 混凝机理 SMOLUCHOWSKI方程
