理想沉淀池的处理效率只与表面负荷有关,即与沉淀池的表面积有关,而与沉淀池的深度无关,池深只与污泥贮存的时间和数量及防止污泥受到冲刷等因素有关。而在实际连续运行的沉淀池中,由于水流从出水堰顶溢流会带来水流的上升流速,因此沉淀速度小于上升流速的颗粒会随水流走,沉淀速度等于卜-升流速的颗粒会悬浮在池中,只有沉淀速度大于上升流速的颗粒才会在池中沉淀下去。而沉淀颗粒在沉淀池中沉淀到池底的时间与水流在沉淀池的水力停留时间有关,即与池体的深度有关。

一、斜管()沉淀池

(1)优点:沉淀面积增大;沉淀效率高,产水量大;水力条件好,Re小,Fr大,有利于沉淀;

(2)缺点:由于停留时间短,其缓冲能力差;对混凝要求高;维护管理较难,使用一段时间后需更换斜板()

(2)缺点:进、出水配水不易均匀;多斗排泥时,每个斗均需设置排泥管(),手动操作,工作繁杂,采用机械刮泥时容易锈蚀。
