PROBLEM TO BE SOLVED: To securely recover magnetic particles from water and prevent them from flowing out to an outside of a water channel system.SOLUTION: In a recovering device 1 of a magnetic particle, a part of an endless chain 10 is arranged above a water surface and the endless chain is moved vertically in a water channel through a drive wheel 7, and sprockets 8, 9. Magnetic rod-like bodies 12 are mounted on the pair of endless chains 10 at a predetermined interval, and magnetic particles such as magnetic sand, ion exchange resin, sludge, active carbon in treated water are attracted to the rod-like bodies 12. The magnetic particles adhered to the rod-like bodies 12 are separated by jetting water by a shower pipe 17 above the water surface, and are recovered at a trough 16 arranged on a lower side of the rod-like bodies 12.SELECTED DRAWING: Figure 1 |
