| abstract | (57) [Summary] [Problem] To prevent solid matter from being deposited around a pump suction pipe arranged in a tank or a pit of a wastewater treatment facility, for example, to pump liquid when the operation of a pump is switched to a spare machine side. To prevent defects from occurring. SOLUTION: An outlet for supply water 66 from a line such as water having a low concentration of solids is provided near a suction port of a pump suction pipe 60, 60 'arranged in a tank 19 of a wastewater treatment facility, and a continuous or continuous outlet is provided at the outlet. Supply water 66 is intermittently supplied. In this way, the supply water 66 is supplied to the pump suction pipe 6. By feeding near the 0, 60 'inlet, Since it is possible to remove solid matter deposited on the suction ports of the pipes 60 and 60 ', poor pumping does not occur when the operation of the pump 20 is switched to the spare machine 20' side. |
