PROBLEM TO BE SOLVED: To repeatedly use processing water by separating processing dust from waste processing water and treating the processing water. SOLUTION: This apparatus for treating processing water is provided with a first water tank and a second water tank into which the waste water from a processing apparatus flows, a third water tank connected to the second water tank, a first partition member for partitioning into the first water tank and the second water tank which are connected to each other in the lower side to downwardly introduce the waste water from the first water tank to the second water tank, a slope provided to be sloped down from the first water tank to the second water tank in the lower side of the first partition member and for depositing the processing dust in the second water tank by the water stream to the second water tank by the first partition member and the free fall of the processing dust, a second partition member for partitioning the third water tank from the second water tank and having an opening formed on the middle part for transferring the water without transferring the processing dust deposited on the second water tank and foam gathered on the water surface and a processing dust recovery means for taking out the processing dust deposited on a prescribed position of the second water tank to the outside of the water tank.
