A backdraft generator according to the present invention comprises a circular support; and a plurality of backdraft generating guide parts placed on the outer circumference surface of the circular support and guiding stream water to the lower region of the circular support by flowing the stream water backward using the speed of the stream, wherein the backdraft generating guide parts include a channel pipeline for forming the vertical stream of the stream water; an inflow part for stream water placed at the upper end part of the circular support and forming one end of the channel pipeline; and a stream water discharge part placed at the other end of the channel pipeline and discharging the stream water. The backdraft generator according to the present invention improves the restoration of water quality by floating pollutants deposited on the bottom of the stream without a separate power source or increasing the concentration of oxygen on the bottom of the stream while the backdraft generator reduces the costs of maintenance, enables mass production thereof owing to the simple structure of the apparatus and the facility of manufacture, and can be made of eco-friendly materials being naturally decomposed. |
