<p><P>PROBLEM TO BE SOLVED: To provide an oxygen dissolving system capable of enhancing effective use efficiency of oxygen and also minimizing influence on an ecosystem with a compact and inexpensive structure. <P>SOLUTION: The oxygen dissolving system supplies water dissolved with oxygen gas to a dissolved oxygen amount improvement water area P where dissolved oxygen amount should be improved. The oxygen dissolving system includes a suction pipe 10 for carrying out intake of low-concentration dissolved oxygen water W<SB>L</SB>having a small amount of the dissolved oxygen amount, an oxygen injection part 12 for injecting oxygen into water inside the suction pipe 10, a vacuum part 16 for generating high-concentration dissolved oxygen water W<SB>H</SB>having a saturated dissolved oxygen amount or higher under the atmosphere, a discharge pipe 18 for discharging the high-concentration dissolved oxygen water W<SB>H</SB>, and a mixing discharge pipe 20 for generating medium-concentration dissolved oxygen water W<SB>M</SB>by mixing the low-concentration dissolved oxygen water W<SB>L</SB>with the high-concentration dissolved oxygen water W<SB>H</SB>to discharge the medium-concentration dissolved oxygen water W<SB>M</SB>to the dissolved oxygen amount improvement water area P. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
