An eco-friendly method for purifying polluted water is provided to purify polluted river water, by discharging lower water within a reservoir through a space between a water gate and a housing when the water gate is opened. A water passage(11) is defined between both support bodies(10). Housing units(20) cover two facing surfaces of the two support bodies. A closed space is defined between the housing unit and the support body. A water gate(30) is composed of a water gate plate(31), lateral plates(32) vertically formed at both sides of the water gate plate, and rotating shafts(33) outwardly protruded from both lateral plates. The rotating shafts are respectively inserted into shaft holes(21) of the housing units. |
