PURPOSE: To ensure that water is purified using a natural purification phenomenon even in an area where a system power supply cannot be obtained by mixing water to be purified with air and releasing the mixture from an air scattering plate in a water purification system which releases air using a solar cell.
CONSTITUTION: If a solar cell 5 starts electric generation, an air is automatically fed by a compressor 6 to be released from an air scattering plate 3. In this case, the air is discharged into the water so that mud at the bottom is not swirled up. In this water purification system, it is important to make oxygen bubbles in the air as fine as possible. This purpose is to increase the migration efficiency of oxygen by making the bubbles fine and feed oxygen slowly and steadily into an area to purified. In order to achieve this purpose, it is necessary to mix water with air prior to the release of the air from the air scattering plate 3, and produce fine bubbles to a maximum permissible extent during the mixing operation. The mixture is released into the water from the scattering plate 3.
