<p>PROBLEM TO BE SOLVED: To provide an apparatus for increasing dissolved oxygen in deep sea water, eliminating the poor oxygen state of cleaned water or deep sea water by one power source, simple equipment, easy operation, reduced power cost, and a vibration noise reducing method without using a compressor and a blower, sending oxygen enriched water to the deep sea water and also using oxygen enriched water of surface layer without generating an air bubble ascending flow in water. SOLUTION: In the dissolved oxygen increasing apparatus, a rotary shaft is extended into water from the surface of the water, and pressure feed blades and a suction pipe are provided to the rotary shaft to be rotated to mix air and water while automatically sucking air to feed water to a pressure feed pipe or an air-liquid separation chamber as oxygen enriched water under pressure and oxygen enriched water is sent into deep water under pressure. Air is discharged to the outside from an air discharge pipe or connected to a separately arranged pipe and allowed to function as an air bubble pump to suck poor oxygen water in deep water to pump up the same to the vicinity of the surface of the water and the sucked water is used as oxygen enriched water to perform the pumping-up of water or the transport of a material into deep water is necessary.</p> |
