PROBLEM TO BE SOLVED: To provide an apparatus for making an oxygen-dissolved treated water capable of simply supplying the treated water in which oxygen is dissolved at a high concentration as drinking water. SOLUTION: The apparatus is composed of an oxygen supply means 2, a pressure vessel 3 and a sub-pressure vessel 31 in which water is stored at a previously set water level or in the full state, a 1st pipe 6 provided to communicate the pressure vessel 3 and the oxygen supply means 2 with each other, a 2nd pipe 34 provided to communicate the pressure vessel 3 and the sub-pressure vessel 31 with each other through a check valve 35 to prevent the back flow of water 4 to the pressure vessel 3 side from the sub-pressure vessel 31 from a water pump 14 capable of supplying the water 4 only to the sub-pressure vessel 31 side from the pressure vessel 3 side and the sub-pressure vessel 31, a 3rd pipe 9 provided to communicate the 1st pipe 6 and the sub-pressure vessel 31 with each other, a 4th pipe 37 provided to communicate the pressure vessel 3 and the sub-pressure vessel 31 with each other, a 5th pipe 40 provided to communicate the 4th pipe 37 and a city water pipe 39 with each other and a 6th pipe 43 provided to communicate to properly discharge/exhaust the water 4 and oxygen 5 in the pressure vessel 3. The oxigen-dissolved water 4 is prepared by increasing the contact area of water 4 with the high concentration oxigen 5 in the sub-pressure vessel 31. COPYRIGHT: (C)2004,JPO
