<p>PROBLEM TO BE SOLVED: To provide a method and a device for increasing dissolved oxygen which lessen the consumption of energy (electric power) and efficiently increase the dissolved oxygen. SOLUTION: The method of increasing the dissolved oxygen of the water existing in the environment, such as sea, lakes and ponds, rivers and canals, comprises supplying the water pumped up from a desired water basin to the upper part of the water of a pipe installed between a desired water depth and the surface of the water and discharging the water to the desired water depth by using a water head. The water of a range within 1 kg/m<3> of the density of the waster is pumped up, by which the dissolution of the oxygen is made >=2 times that of the saturated dissolved oxygen in the atmosphere air.</p> |
