设备简介EQUIPMENT INTRODUCTION:

竖流式沉淀池又称立式沉淀池,是池中废水竖向流动的沉淀池。池体平面图形为圆形或方形,水由设在池中心的进水管自上而下进入池内(管中流速应小于30mm/s) , 管下设伞形挡板使废水在池中均匀分布后沿整个过水断面缓慢上升(对于生活污水一般为0.5-0.7mm/s ,沉淀时间采用1-1.5h) , 悬浮物沉降进入池底锥形沉泥斗中,澄清水从池四周沿周边溢流堰流出。竖流式沉淀池又称立式沉淀池,是池中废水竖向流动的沉淀池。池体平面图形为圆形或方形,水由设在池中心的进水管自上而下进入池内(管中流速应小于30mm/s) ,管下设伞形挡板使废水在池中均匀分布后沿整个过水断面缓慢上升(对于生活污水一般为0.5-0.7mm/s ,沉淀时间采用1-1.5h) , 悬浮物沉降进入池底锥形沉泥斗中,澄清水从池四周沿周边溢流堰流出。堰前设挡板及浮渣槽以截留浮渣保证出水水质。池的一边靠池壁设排泥管(直径大于200mm )靠静水压将泥定期排出。竖流式沉淀池的优点是占地面积小,排泥容易,缺点是深度大,施工困难,造价高。常用于处理水量小于20000m3/d的污水处理厂。

理论依据:竖流式沉淀池中,水流方向与颗粒沉淀方向相反,其截留速度与水流上升速度相等,上升速度等于沉降速度的颗粒将悬浮在混合液中形成一层悬浮层 ,对上升的颗粒进行拦截和过滤。因而竖流式沉淀池的效率比平流式沉淀池要高。

Vertical sedimentation basin is also called the vertical sedimentation tank, vertical flow is pool waste water in the tank. Pool body plane figure as the round orsquare, the center of the water in the pool feed line from top to bottom into the pool (in pipe flow rate should be less than 30 mm/s), tube consists of umbrella-shaped baffle to make waste water in the pool is uniformly distributed along the whole section slowly rising water (for sewage generally 0.5 0.7 mm/s, precipitationtime with 1-1.5 h), suspended solids settlement sank into the bottom cone bucket, clear water from the pool along the perimeter around the overflow weir flow out.Vertical sedimentation basin is also called the vertical sedimentation tank, vertical flow is pool waste water in the tank.

IWeir before set a baffle and scum trough to intercept scum guarantee water quality. One side of the pool set exhaust pipe on the wall (greater than 200 mm indiameter) by hydrostatic pressure to mud discharge on a regular basis. The advantage of vertical flow sedimentation tank is cover an area of an area small, easy todredge, defect is deep, construction difficulty and high cost. Often used for processing water is less than 20000 m after a/d sewage treatment plant.

Theoretical basis: the vertical sedimentation basin, in the direction of flow and particle precipitation in the opposite direction, the intercept rise speed and flow rateare equal, rising velocity equal to the settling velocity of particles will be suspended in the mixture to form a suspension layer, to intercept and rise of particle filter.Thus the efficiency of the vertical sedimentation basin is higher than flat sedimentation basin.

结构原理STRUCTURE PRINCIPLE:

竖流式沉淀池的工作原理:在竖流式沉淀池中,污水是从上向下以流速v做竖向流动,污水中的悬浮颗粒有以下三种运动状态:

①当颗粒沉速u>v时,则颗粒将以u-v的差值向下沉淀,颗粒得以去除;

②当u=v时,颗粒处于随机状态,不下沉亦不上升;

③当u<v时,颗粒将不能沉淀下来,而会被上升水流带走。

The working principle of vertical sedimentation basin: in the vertical sedimentation tanks, sewage from down to do the vertical flow velocity v, suspended particlesin wastewater has the following three motions: 

(1) when particles sinking speed u > v, the particles will u . v is the difference between the precipitation down, to theremoval of particles; 

(2) when u = v, particles in a random state, not sinking nor rise; 

(3) when u < v, particles will not settle, and will be taken away by rising water.
