Title:
WATER TREATMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/024349
Kind Code:
A1
Abstract:
This water treatment apparatus (100) comprises a treatment tank (110) and a separator (130). The separator (130) is positioned inside the treatment tank (110) and separates magnetic-powder-containing activated sludge (2) from water (1) to be treated. The separator (130) includes a drum (131), a superconducting magnet (132), a scraper (133), and a magnetic shield (134). The superconducting magnet (132) magnetically attracts the magnetic-powder-containing activated sludge (2) to a peripheral surface (131a). The scraper (133) is capable of scraping away the magnetic-powder-containing activated sludge (2). The magnetic shield (134) is a superconducting body. The magnetic shield (134) is positioned along the rotation direction (R) on the inner side of the peripheral surface (131a) so as to face a sliding contact part (133a) with the peripheral surface (131a) interposed therebetween. The magnetic shield (134) is positioned at a different position than the superconducting magnet (132) in the rotation direction (R).
