Pump washing sedimentation tank capable of being recycled

The invention discloses a pump washing sedimentation tank capable of being recycled, which is applied to the technical field of sedimentation tanks and is characterized in that channel steel is used as a keel at the bottom of a turnover sedimentation tank body, so that the overall load is dispersed and uniformly falls on a top plate of a basement, and floor cracking caused by overlarge load of the top plate is avoided; during hoisting, the fixed hoisting ring can slide upwards to a preset position and extrude the elastic pressurizing air bag, the air pressure in the turnover settling box body is increased, the air in the turnover settling box body can push the color developing rod to rotate through the elastic pushing hose, and a worker can judge whether the turnover settling box body is damaged or not by observing the color of the color developing rod; and secondly, the colored powder is fully mixed in the turnover precipitation box body, the worker can quickly determine a leakage point by observing the colo
