摘要
通过计算模拟二沉池流态,解决了二沉池流态测定的难题,该模拟方法速度快、精度高、不需要实型池.通过对实际池的计算发现,周边式二沉池上溢流集中在靠池周边的区域,以垂直向上的流线为主,池中心上部存在着较大的水流死区,由此解释了该类型池澄清能力小的原因.
Secondary clarifier flow pattern is simulated by computer operation, which solves the problem of measuring secondary settler flow pattern. This method is quick and accurate and no real settling pool is needed. It is found by this method that the overflow of peripheral feed-peripheral effluent secondary settler is mainly on periphery zone of the pool where flow lines are nearly vertical and there is a large flow still area in the upper center part of the settler, which explains the reason for the low clarification capacity of this type of clarifier.
