An apparatus for increasing dissolved oxygen in water is provided to decrease the installation space and increase the concentration of dissolved oxygen efficiently, by improving the structure of the apparatus. A tank(90) stores water supplied from the outside. An oxygen-dissolving unit(50) is installed in the tank. A first air suction port(37) supplies purified air from a lateral surface of the tank. A second air suction port(47) supplies purified air from an upper portion of the tank. A high-pressure line(11) jets water of high-pressure into the tank by using a high-pressure pump(10) installed outside the tank. A high-pressure nozzle(12) is connected to an end of the high-pressure line, and installed at a lower end of the second air suction port. The high-pressure nozzle jets water downwardly. An air suction and jet port(57) is disposed below the second air suction port such that the air suction and jet port is distanced from the second air suction port at a distance of 0.2-0.3 mm. A sucked air-jetting case(56) is connected to the high-pressure nozzle, the second air suction port, and the first air suction port. The air suction and jet nozzle is installed within the sucked air-jetting case. A ceramic collision plate(58) is installed below the sucked air-jetting case to bounce air and water jetted through the air suction and jet port. Further, the apparatus for increasing dissolved oxygen in water additionally contains a recycling line and a circle type water film plate. |
