A waste water treatment system using a superconductive magnetic separator capable of efficiently washing a magnetic filter. The laminated magnetic filter formed by detachably laminating unit magnetic filters is installed in the bore of a superconductive magnet, and the overall length of the laminated magnetic filter is made at least equal to or longer than the longitudinal length of the superconductive magnet. During the excitation of the superconductive magnet, the unit magnetic filters are removed from the upstream side (sewage side) of the laminated magnetic filter by pushing the unit magnetic filters to the downstream side (fresh water side) thereof, and after washing, returned again to the downstream side.
