In an air pollution control device, a ship, and a water supply method, an exhaust gas recirculation line (G4), a scrubber (42), an air cooler (52), and a drain water supply line (W4) are provided. Through the exhaust gas recirculation line (G4), a part of an exhaust gas discharged from a marine diesel engine (11) is compressed by a turbocharger (21) and recirculated to the marine diesel engine (11) as combustion air. The scrubber (42) injects water into the exhaust gas which flows through the exhaust gas recirculation line (G4) to remove a toxic substance. The air cooler (52) cools a mixture gas compressed by a compressor (22). The mixture gas is obtained by mixing air and a recirculation gas which has been subjected to the removal of a toxic substance by the scrubber (42). Through the drain water supply line (W4), drain water generated by the cooling of the exhaust gas by the air cooler (52) is supplied to the scrubber (42). With the configuration, an increase in size and cost of the device can be suppressed by effectively using treated water.
