The settled sludge is then returned to the ditch via a sludge return pumping system.
固定的污泥然后回到沟里经由污泥回归泵系统。
In this paper, beaker experiment was done by methods of sludge return, and carry out a highly efficient solid-liquid separation study of the dynamic test.
本文利用污泥回流方法进行了烧杯实验,并开展了高效固液分离器的动态实验研究。
If any of return sludge pumps is in off mode, it will be regarded as standby unit. If fault is found on duty pump, the standby pump will be automatically change over.
没有启动的污泥回流泵作为备用泵,如主泵发生故障,备用泵自动切入。
