有污泥斗用来积聚沉淀下来的污泥，多设在池前部的池底以下，斗底有排泥管，定期排泥。
沉淀池一般是在生化前或生化后泥水分离的构筑物，多为分离颗粒较细的污泥。在生化之前的称为初沉池，沉淀的污泥无机成分较多，污泥含水率相对于二沉池污泥低些。位于生化之后的沉淀池一般称为二沉池，多为有机污泥，污泥含水率较高。
及时排泥是沉淀池运行管理中极为重要的工作。污水处理中的沉淀池中所含污泥量较多，有绝大部分为有机物，如不及时排泥，就会产生厌氧发酵，致使污泥上浮，不仅破坏了沉淀池的正常工作，而且使出水质恶化，如出水中溶解性BOD值上升；pH值下降等。
初次沉淀的池排泥周期一般不宜超过2日，二次沉淀池排泥周期一般不宜超过2小时，当排泥不彻底时应停池（放空）采用人工冲洗的方法清泥。
机械排泥的沉淀池要加强排泥设备的维护管理，一旦机械排泥设备发生故障，应及时修理，以避免池底积泥过度，影响出水水质。

为避免短流，一是在设计中尽量采取一些措施（如采用适宜的进水分配装置，以消除进口射流，使水流均匀分布在沉淀池的过水断面上，降低紊流并防止污泥区附近的流速过大，采用指形出水槽以延长出流堰的长度；
沉淀池加盖或设置隔墙，以降低池水受风力和光照升温的影响；高浓度水经过预沉，以减少进水悬浮固体浓度高产生的异重流等）。
二是加强运行管理，在沉淀池投产前应严格检查出水堰是否平直，发现问题，要及时修理。在运行中，浮渣可能堵塞部分溢流堰口，致使整个出流堰的单位长度溢流量不等而产生水流抽吸，操作人员应及时清理堰口上的浮渣；
用塑料加工的锯齿形三角堰因时间关系，可能发生变形，管理人员应及时维修或更换，以保证出流均匀，减少短流。通过采取上述措施，可使沉淀池的短流现象降低到最小限度。

沉淀池包括初次沉淀池和二次沉淀池，初次沉淀池是一级污水处理厂的主题处理构筑物，包括平流沉淀池，辐流沉淀池和竖流沉淀池。初沉池的主要能耗设备是排泥装置，污泥泵等；二次沉淀池的能耗主要是在污泥的抽吸和污水表明漂浮物的去除上，能耗比较低。杭州艾迪机器提醒您，然后就是进行污泥处理工艺，污泥通过污泥泵运输至浓缩池，进行污泥脱水，干燥。
