PROBLEM TO BE SOLVED: To provide an apparatus 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 having high oxygen partial pressure and capable of supplying oxygen, a pressure vessel 3 in which water is stored at a previously set water level or in the full state, a 1st pipe 6 and a 2nd pipe 7 inserted and supported in the pressure vessel 3, a 1st valve 10 provided between the oxygen supply means 2 and the 1st pipe 6 to be interposed, a water pump 14 provided between the 1st pipe 6 and the pressure vessel 3 to be interposed and a 2nd valve 12 for exhausting gas and discharging liquid which is provided between the 1st valve 10 and the water pump 14 to be interposed. The oxygen-dissolved water is prepared by increasing the contact area of water with the high concentration oxygen in the pressure vessel 3. COPYRIGHT: (C)2004,JPO
