A ballast water treatment device 1 includes a ballast tank 60, a main pipe 2, a circulation pipe 80, and a sterilizing component-introducing unit 40. The circulation pipe 80 returns ballast water stored in the ballast tank 60 to the main pipe 2. The main pipe 2 guides ballast water to the ballast tank 60. The sterilizing component-introducing unit 40 introduces a sterilizing component to a downstream side of a part of the main pipe 2 connected with the circulation pipe 80. In a process of returning a part of ballast water stored in the ballast tank 60 to the ballast tank 60 via the circulation pipe 80 and the main pipe 2, by pouring a sterilizing component from the sterilizing component-introducing unit 40, a sterilizing component can be added to the ballast water. Accordingly, the ballast water treatment device 1 enables a sterilizing component concentration of ballast water to be increased.
