Abstract
PURPOSE: To reduce installation expense by connecting a branch pipe to the discharge pipe of an underwater pump, and providing a nozzle for stirring scum accumulated on the water surface of a sewage tank to the branch pipe. CONSTITUTION: When the level of sewage flowing in a manhole rises and reaches the high water-level H1 , a high water level switch 4b for high water- level is actuated to allow the fist underwater pump 12 to operate. Next, when sewage is pumped up by a pump 12, pressurized water separated from a drain pipe 6 is discharged from each nozzle 8a, 8b, 8c via a branch pipe 7. Then, a pressurized water of the nozzle 8a is discharged to the scum S side accumulated and solidified on the surface of sewage to crush the scum S. Also, a pressurized water of the nozzle 8b stirs crushed scum S to be mixed in water. As the water level further lowers, an upper part of the pump 2 is exposed, and the pump 2 is cooled by a pressurized water of the nozzle 8c.
