<P>PROBLEM TO BE SOLVED: To provide an oxygen dissolution promoter, capable of efficiently improving oxygen dissolving degree of the whole rainwater fed to a culture pond or the like. <P>SOLUTION: This promoter includes: a treatment tank; a rotary driving source; a rotating shaft; a diffuser tube; an air supply means; and an agitation deaeration means. The treatment tank includes: a water supply means; and a draining means for maintaining the inside of the tank at a fixed water level and guiding the water in the tank to a promotion pond such as the culture pond or a water tank which is the next step. The rotating shaft is disposed in a vertical shaft-like fashion in the treatment tank, and freely rotated by the rotary driving source. The diffuser tube is fitted around the rotating shaft, freely rotated horizontally together with the rotating shaft in the treatment tank, and also adapted to freely jet micro bubbles on receiving the supply of air from the air supply means. The agitation deaeration means is disposed longitudinally at an outer peripheral position apart from the rotating shaft, freely driven in rotation together with the rotating shaft in the water in the tank, and also adapted to separate and raise the dissolving gas such as nitrogen and carbon dioxide contained in rainwater with the agitation in the interior while taking the rainwater from a water intake port formed on the peripheral surface thereof and dissipate the same upward. <P>COPYRIGHT: (C)2013,JPO&INPIT |
