Chemical adding and flushing device for clean water tank of water supply pressurization station

The invention discloses a dosing and flushing device for a clean water tank of a water supply pressurization station. The dosing and flushing device comprises the clean water tank, a water delivery pump and a dosing room, the output end of the water delivery pump is communicated with a water delivery pipe, the water delivery pipe is communicated with a plurality of flushing pipes in parallel, the plurality of flushing pipes are distributed on the side wall and the bottom surface in the clean water tank, the plurality of flushing pipes are communicated with a plurality of flushing nozzles, and the plurality of flushing nozzles are distributed on the inner side wall and the bottom surface of the clean water tank; the output end of the dosing room is communicated with the water conveying pipe; therefore, when the water delivery pump is used for cleaning the clean water tank, chemicals can be added into water by the chemical adding chamber, and high-pressure water containing the chemicals is ejected by the flushi
