Description of the Related Art Conventionally, in a garden pond, a fish pond, or a sewage treatment tank, organic substances and the like are accumulated, and a bad odor is generated due to the decomposition of the organic substances, and water-bloom and algae are generated due to eutrophication. Then, as a countermeasure, there is a device that sprays a water flow into the air by a fountain device to dissolve the air into the water to activate aerobic bacteria and accelerate the decomposition of organic matter (for example, Japanese Patent Publication No. 3-7437). ). Further, a device that connects an air supply pipe to a suction part of a pump installed in water to generate a gas-liquid mixed flow and aerobically purifies sewage by using microorganisms is well known (for example, Fair 2-25677

き、悪臭も発生しないものである。When the pump of the circulation aeration apparatus configured as described above is operated, the water pumped from the bottom of the water is sent to the water storage tank, the jet water is discharged from the injection nozzle to the upper radial direction, and the jet water flows in the air. It flies and is struck on the surface of the water while entraining the air, causing the air to melt into the water. At this time, since the discharge pressure or the flow rate of the injection nozzle is made different according to the shape of the pond or the like, the water sucked up by the submersible pump is supplied to the peripheral portion of the pond or the like. Then, since the water below the submersible pump in which the air is less melted is sucked, the water in the peripheral portion moves to the circulation aeration device, and the entire water in the pond or the like can be circulated. In this way, the air-dissolved water can be circulated in a wide range, the microorganisms can be activated, the decomposition of organic matter and the generation of water-bloom, algae, etc. can be suppressed, and no foul odor is generated.

できるものである。The present invention is configured as described above,
By injecting jet water with a circulation aeration device, it is possible to circulate the entire water of the pond and aerate at the same time. That is, in the conventional aeration device, since the air-added gas-liquid mixed water is jetted near the aeration device, the water in which the air is dissolved is sucked again by the aeration device, and the bypass circulation water channel is formed. Water distant from the device stagnated, and it was not possible to supply dissolved water of air to the whole pond etc.
In the present invention, in consideration of the position of the circulation aeration device installed in the pond and the distance to the water side, the discharge pressure of each injection nozzle is adjusted so that the flight distance of the jet water reaches the water side. Therefore, it is possible to circulate the dissolved water of the air by supplying the dissolved water of the air to the distant place and sucking it from the lower side of the circulation aeration device. Therefore, aerobic bacteria are activated in the entire pond and the like, the decomposition of organic matter is promoted, and the generation of water-bloom and algae can be suppressed.
