<p>In the present invention, provided is a device for purifying water quality which supplies air among the atmosphere as bubble state to reservoirs or artificial lakes with fewer water flows, which are built for creating green environment in cities, thereby increasing dissolved oxygen amounts and preserving water quality. More specifically, the present invention relates to a device for purifying water quality using a water-turbine type aerator, which supplies air among atmosphere as bubble states to reservoirs or artificial lakes with fewer water flows, thereby increasing dissolved oxygen and preserving water quality. The device comprises a pair of lifting guide bars which are vertically inserted in standing by using a base facility installed on the bottom floor of the reservoir; a buoy integrated into a lifting frame which goes up and down along with the pair of the lifting guide bars; and a water-turbine type aerator built in the buoy. Therefore, the device installed and fixed in the reservoirs causes water current and purifies water quality in the reservoirs by moving up and down above the level of water.</p> |
