脉冲澄清池和其它类型的澄清池一样,都是充分利用已沉淀于池中的絮凝体(泥渣)表面的活性,将原水中的悬浮物吸附、粘附、凝聚成较大颗粒的絮凝体,从而造成与水分离的有利条件。脉冲澄清池与其它类型的泥渣过滤(悬浮体接触)澄清池相比较,其主要特点是:悬浮泥渣层处于由下向上和由上向下的周期性的往复运动状态,即脉动状态。为造成这种状态,势必周期性地向池中投配定量的原水。在水源连续,均匀地向脉冲澄清池供水的情况下,就必须在脉冲澄清池进水头部采取措施,将连续均匀供水改变为周期性地变量供水。采用真空式、虹吸
The pulse clarifier, like other types of clarifiers, utilizes the activity of the surface of the flocs (slime) that have been deposited in the pool, and adsorbs, adheres, and agglomerates the suspended solids in the raw water into larger particles. , thereby creating favorable conditions for separation from water. Compared with other types of sludge filtration (suspension contact) clarifiers, the main features of the pulse clarifier are: the suspended sludge layer is in a periodic reciprocating state from bottom to top and top to bottom, that is, pulsation. In order to cause this state, it is bound to periodically dose quantitative raw water into the pond. In the case where water is supplied continuously and evenly to the pulse clarifier, measures must be taken at the inflow head of the pulse clarifier to change the continuous uniform water supply to periodically variable water supply.
