斜板（管）沉淀池

InclinedPlate(Tube)SedimentationTank斜管沉淀池的原理

PrincipleofInclinedTubeSedimentationTank?沉淀效率公式

Formulaofsedimentationefficiency沉淀池面积越大，沉淀池的沉淀效率就越高。

Thelargertheareaofthesedimentationtankis,thehigherthesedimentationefficiencywillbe.沉淀池越浅，沉淀时间就越短。

Theshallowerthesedimentationtankis,theshorterthesedimentationtimewillbe.

因为:L/H=v/uo所以

L/H=v/uo,so（1）L、v不变，H越小，则u0越小;IfLandvarekeptunchanged,thesmallerHis,thesmalleru0willbe;（2）u0、v不变，H→H/3，则L→L/3;Ifu0andvarekeptunchanged,HbecomesH/3,thenLwillbeL/3;（3）u0、L不变，H→H/3，则v→3v，Q→3Q;Ifu0andLarekeptunchanged,HbecomesH/3,thenvwillbe3vandQwillbe3Q;斜板沉淀池具有沉淀效率高、停留时间短、占地少、处理效果稳定等优点。

PrincipleofInclinedTubeSedimentationTank

一定角度（60°左右)的板（管）状组件

Plate(tube)assemblywithacertainangle(about60°)水流:从上向下//下向上流动

Waterflow:fromtoptobottom//frombottomtotop颗粒斜管底部:自动下滑

Particles:sedimentatthebottomoftheinclinedtubes,andthenslidedownautomatically其沉淀面积明显大于平流式沉淀池

Itssedimentationareaisobviouslylargerthanthatofhorizontalflowsedimentationtank可提高单位面积的产水量、沉淀效率
