摘　　要：浑水异重流是沉淀设备中水流的基本特征,不仅存在于高浊度水沉淀池中,也存在于一般浊度水的沉淀设备中.不同型式的沉淀设备,对浑水异重流的适应性不同.平流沉淀池由池末端表面集水,能较好地适应浑水异重流的特性,其中上向流斜板(斜管)沉淀设备对浑水异重流的适应性最好,其次是平向流斜板,下向流斜板适应性最差.The density current of turbid water is the basic characteristic of the water current in sedimentation tank, in both the high turbid water and the general turbid water. Different sedimentation tanks have the different adaptability to the density current of turbid water. The horizontal stream sedimentation tank (HSST) has a good adaptability to the characteristic of the density current of turbid water because of its collecting water at the end surface of the tank. Among different types of HSST, the up-stream declined plate (tube) sedimentation tank has the best adaptability, and the type of horizontal-stream plate (tube) sedimentation tank is normal, but the worst is the type of down-stream declined plate sedimentation tank.
