Abstract
A magnetic separation apparatus comprising: a separation vessel into which waste water containing a coagulated magnetic floc is supplied; a drum separator that is provided in the separation vessel and adsorbs the magnetic floc with a magnetic force while being rotated; a scraper that is abutted against a surface of the separator and scrapes the magnetic floc adsorbed by the surface of the separator; a scraper guide that is connected to the scraper and discharges the magnetic floc scraped by the scraper; and a scraping brush that scrapes the magnetic floc scraped by the scraper from the scraper and guides the magnetic floc to the scraper guide, wherein a lower portion of the separator is submerged in the waste water in the separation vessel, a rotational direction of the separation vessel in the waste water is set to the same direction as a flow direction of the waste water flowing in the separator, and a rotational direction of the scraping brush is set to a direction opposite to the rotational direction of the separator.
