Since the density of the water-oil separator 5 is between the density of oil and the density of water, the first separator 29 rises under the buoyancy of water, the separation hole 25 opens, and water flows out from the gap between the first separator 29 and the cone hole 24 and enters the water pool 23. The drain hole 26 is opened and the water is discharged from the drain hole 26. When all the water in the oil pool 4 flows into the water pool 23 and the oil layer contacts the first separator 29, since the density of the first separator 29 is greater than that of the oil, the first separator 29 falls under its own gravity, and the separation hole 25 is closed, thereby preventing oil from flowing into the water pool 23 from the separation hole 25. The oil drain hole 6 is opened and the oil is discharged from the oil drain hole 6.
