PURPOSE: A ship is provided to allow acid water and alkaline water, generated when seawater is electrolyzed, to purify exhaust gas and ballast water and to treat waste water. CONSTITUTION: A ship(10) comprises a ballast tank(130), an exhaust pipe(150), an electrolyzer(200), an acid water supply line(L2), and an alkaline water supply line(L3). The ballast tank controls a draft of the ship. The exhaust pipe guides exhaust gas generated in an engine to the outside of the ship. The electrolyzer electrolyzes seawater to generate acid water and alkaline water. The acid water supply line is connected to the electrolyzer to supply the acid water to the ballast tank and the exhaust pipe. The alkaline water supply line is connected to the electrolyzer to supply the alkaline water to the exhaust pipe.
