A ship ballast water treatment apparatus according to an embodiment of the present invention includes a sterilizing device for sterilizing ballast water flowing into or out of a ballast tank of a ship, A guide rail installed to guide movement of the sterilizing device, and a landing space provided on the top surface of the sterilizing device.

The sterilization apparatus may include a ballast water inlet and a ballast water outlet, and the ballast water inlet and the ballast water outlet may be respectively equipped with an on-off valve.

The ballast water inlet and the ballast water outlet are connected to the inlet pipe and the outlet pipe, respectively, and the inlet pipe and the outlet pipe may be made of a flexible material.

The sterilizing device may be disposed in a space between the upper deck of the vessel and the secondary deck below the upper deck.

When the sterilizing device is moved along the guide rail, the inlet pipe and the outlet pipe can be separated from the sterilizing device.

By utilizing the top surface of the sterilizing device as a landing space, the ballast water treatment apparatus according to an embodiment of the present invention makes it possible to efficiently use the landing space space that was left empty during transportation of ship-related equipment.
