A ballast water treatment device including a cylindrical filter (2) that is disposed in a casing (1) and filters and externally discharges ballast water having flowed inside, comprising: a filter rotating unit (3) that rotates the filter (2) around a shaft center of the filter (2); a suction nozzle (4) that is disposed on the primary side of the filter (2) and opens toward the inner circumferential surface of the filter (2); a waste rinsing water discharging unit (5) that externally discharges waste rinsing water sucked by the suction nozzle (4) from the casing (1); a high-pressure fluid jet nozzle (40) that is disposed on the secondary side of the filter (2), opens toward the outer circumferential surface of the filter (2), and jets high-pressure fluid toward the filter (2); and a high-pressure fluid supplying unit (41) that supplies high-pressure fluid to the high-pressure fluid jet nozzle (40). The ballast water treatment device enables rinsing of the filter (2) to be performed efficiently and effectively, and achieves a simple structure and facilitated manufacture and maintenance.
