In existing MBR sewage disposal systems, the outfall sewer of membrane module is connected directly with suction pump, for film work
Journey treating capacity is more than daily 200 tons of down-stream processing system, and the rotating speed of suction pump is larger, due in pipeline in aspiration procedure
Can air entrainment, after working long hours, in pipeline increases of air capacity can influence the velocity of discharge of clear water, cause suction pump sky
Turn, therefore generally require the water outlet installation liquid level gauge in membrane module in real work for observing water outlet status, works as liquid level
It being then stopped when relatively low, the air in manual discharge conduit, this vacuum pumping method is time-consuming longer, and sludge age is caused to increase, because
It is the current technical issues that need to address that this, which finds a kind of method easily vacuumized in time,.
