| 摘 要： | 异重流是挟沙水流的一种特殊运动形式,它的出现给净水工艺带来了极其不利的影响,为了提高其沉淀效果,防止或减弱池中异重流,就异重流对悬浮物沉淀过程的影响进行了分析,并根据沉淀过程所受的影响特点,对沉淀池进行了改造,使水力条件得以改善、沉淀效果得到明显提高.

| Abstract: | Density current is the special kinematic form of sediment-laden flow, which is extremely unfavourable to the water purification technique. In order to improve settling effect, forestall and weaken density current,influence of density current on the settling process of suspended particulate matter are analysed, and acconting to the influential characteristics of the settling process,the settling tank.is transformed. The settling effect is obviously made better because hydraulic condition is improved. |

| Keywords: | density current horizontal-flow sedimentation basin settling effect |
