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