摘　　要：根据水厂工艺参数计算实际生产过程中混凝各阶段的速度梯度和停留时间,并在混凝搅拌程序中采用同样的速度梯度和停留时间,且据此计算出混凝搅拌各阶段的叶片转速,所得混凝烧杯搅拌程序能较好地模拟实际生产的混凝水力条件,对实际生产的混凝剂投加具有较好的指导意义。Computed the velocity gradient and retention time of the actual production process on the bass of the waterworks process parameters, used the same velocity gradient and retention time in the coagulation mixing procedure, and then computed the rotor speeds of each coagulation mixing stage. The established coagulation mixing procedure can simulate the hydraulic condition of actual production well and has googuiding significance on the coagulant dosing of the actual production.
