ABSTRACT:
A magnetic separation filtering and cleaning apparatus for adding flocculant and magnetic powder to raw water containing pollutant particles to form magnetic floc in treated fluid and separating and removing the magnetic floc from the treated fluid, comprising: a magnetic field generation device being provided in a rotating body for suctioning the magnetic floc on a surface of the rotating body from the treated fluid containing the magnetic floc, a magnetic field rotating device for rotating the magnetic field generation device, a sludge recovery device for separating sludge including the magnetic floc mechanically from the surface of the rotating body of the magnetic field generation device; and a filtering device having a rotating net for filtering out the magnetic floc from the treated fluid including the magnetic floc and flowing down the treated fluid filtered through the rotating net.
