This disclosure describes a magnetic separation apparatus and a magnetic separation method, and a wastewater treatment apparatus and a wastewater treatment method that allow to obtain clear treated water only with the magnetic separation apparatus without using a filter. Lower halves of two disks arranged in a separation tank are under wastewater when it flows thereinto. A supply portion of the wastewater is provided on one upper wall surface of the separation tank, the wall surface being located upstream in a rotational direction of the disks. In addition, an outlet portion of treated water is provided on the other upper wall surface, the wall surface being located downstream. Consequently, a flow direction of the wastewater and the rotational direction of the disks are the same as each other, a force that detaches magnetic flocs having adhered to the disks is substantially reduced, and thus the filter becomes unnecessary.. |
