Title:
MAGNETITE REGENERATION APPARATUS USING SEPARATION TANK AND MAGNETITE REGENERATION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/050144
Kind Code:
A1
Abstract:
The present invention is a magnetite regeneration apparatus (A) for regenerating magnetite (Fe3O4) mixed in contaminated water in order to adsorb phosphorous in a water treatment apparatus (10), the magnetite regeneration apparatus (A) comprising: a washing tank (100) holding washing water (W) for washing off phosphorous adsorbed on the surface of magnetite (Fe3O4); a separation tank (200) for receiving, via an ejection part (110) formed on the lower part of the washing tank (100), the magnetite (Fe3O4) having the phosphorous removed therefrom, and the washing water (W), and separating the magnetite (Fe3O4) and the washing water (W); and a magnetite storage part (300) and a washing water storage part (400) connected to the separation tank (200) and storing the magnetite (Fe3O4) and the washing water (W), respectively, that were separated in the separation tank (200). In this case, the magnetite (Fe3O4) that adsorbed the phosphorous in the water treatment apparatus (10) is fed into the washing tank (100) and washed using the washing water (W). The washed magnetite (Fe3O4) is transferred with the washing water (W) to the separation tank (200) and rapidly separated, and then stored in the magnetite storage part (300). The magnetite regeneration apparatus (A), according to the present invention, enables magnetite (Fe3O4) having phosphorous adsorbed to the surface thereof to be rapidly washed using washing water (W) and rapidly separated from the washing water (W) so as to be reused.
