PROBLEM TO BE SOLVED: To provide a device for washing sedimentation and removing impurities where impurities are efficiently separated from sedimentation recovered from a sedimentation basin, or the like, using a pump, and thereafter, the sedimentation subjected to washing and impurities can be removed/exhausted, respectively individually. SOLUTION: This device is composed of: a sedimentation separating-washing tank 1 in which the lower part has a hopper shape, and the upper part is provided with a rectification barrel 6 for washing sedimentation by stirring with a generated rotating flow; a screw conveyer 2 for washing and conveying sedimentation arranged at the lower part of a hopper part 11; a plurality of upward flow tubes 4 at the upper position of the screw conveyer 2 fitted per prescribed intervals over the whole conveying process in the conveying direction by the screw conveyer 2 and sucking up the impurities utilizing upward flows; and an impurity separating apparatus 3 for removing only the impurities separated and suspended in the sedimentation separating-washing tank 1.
