摘　　要：本文详细讨论了坎布混凝动力学的速度梯度公式,该公式虽然是在层流条件下得出的,但在机械搅拌情况下可以用来判别紊流混凝的水力条件;并提出和论证了紊流涡旋在混凝反应中的动力学作用,且用涡旋理论解释了厌氧反应器中生物絮凝现象。A velocity gradient formula of Camp' s coagulation dynamics is discussed in detail in the paper. Although the formula is derived under the laminar flow condition, it may be used to judge hydraulic condition of turbulent coagulation under the circumstance of mechanical stirring.Meanwhile the dynamic action of vortex in coagulative reaction is proved and biological flocculation phenominon in the anaerobic reaction is explained with vortex theory.
