sludge settling

The terminal settling velocity was much greater than that of the liquid upflow, which successfully solved the problem of sludge wash-out under high organic loading rate ( OLR).

颗粒污泥的终端沉降速度远高于厌氧反应器中废水的上流速度，其良好的沉降性能解决了在高负荷情况下污泥的流失问题。

The sludge treatment of Minhang Water Works which used Huangpu River water as source was studied. Through sludge settling characteristics study, a process which consisted of collection, thickening, equalization, PAM dosing, solid liquid separation by centrifuge, PLC central control was adopted.

针对黄浦江水系闵行水厂排泥水的处理，通过污泥沉降特性研究，采用收集、浓缩、平衡、投加聚丙烯酰胺（PAM）、离心机固液分离的工艺流程和PLC中央控制，提高了自动化程度。

There are two side tanks for alternating outlet. Additional settling tank, sludge and mixed liquor recirculation equipment are omitted. This process runs at constant water level with small water head loss. Power consumption is greatly saved because of low power load.

其中有两个边池交替出水，不需要单独设置沉淀池，省却了污泥和混合液回流设备，恒水位运行，水头损失小，装机负荷低，可以大大节省动力消耗。
