摘　　要：通过集成垂向异重流式混合流体水沙分离鳃的动水沉降试验,分析了沉淀时间、进流速度与溢流浓度的关系,并对溢流液体进行了颗分试验。试验表明,通过控制进流速度,可以调节溢流浓度的大小。动水沉降试验在一定程度上可以达到泥沙在静水沉降时的效果,对加速水沙分离的效果明显。The experiment was conducted to study and analyze the relationship between sedimentation time,incoming flow velocity and overflow consistency and to test grain distribution of overflow liquid.The experiment results indicated that the overflow consistency could be adjusted by controlling velocity of the incoming flow.To some extent,the integration separation device in dynamic water sedimentation could achieve the same effect as the immobile sedimentation,it could accelerate the obvious effect of water-sediment separation.
