Abstract
PURPOSE: To perform a continous and stable filtering treatment without clogging in a magnetic filtering device by subjecting magnetic particles to which substances to be treated are adhered to a magnetic treatment in advance to remove coarse particles.
CONSTITUTION: The waste water 1 containing suspended solids is regulated its pH by the pH regulator 2, passed through the magnetic seed-adding tank 3, the coagulating tank 4 where the magnetic seed and substances to be treated are coagulated together, the magnetic adsorption tank 5, and the magnetic filtering device 6, and then discharged as the treated water 7 to the outside. The suspended solids to be treated contain, besides the usual non-, dia- and weak-magnetic suspended solids, unicellular organisms, e.g., bacterial, alga, etc. The method features the installation of the magnetic adsorption tank 5 before the magnetic filtering device 6. In the magnetic adsorption tank 5, a Ba-Fe2O3 magnet is provided at the bottom of the tank or above the liquid surface. Thus, comparatively coarse particles of the coagulated particles consisting of the magnetic seed and the substances to be treated can be adsorbed on the magnet and then removed from the original water.
