<p>A polluted river water purification method is provided to purify polluted river water by discharging bottom water of the water reservoir side of a water gate through a siphon passage formed between a water gate and a siphon operation plate. A polluted river water purification method is used for purifying polluted river water by installing a water gate(10) to be inclined toward the discharge side with no power, installing many rubber dam members(50') which are increased or decreased in the volume by air injection to contact with the discharge side of the water gate to stand up or overturn the water gate to the bottom of the discharge side of the water gate at regular intervals, locating a siphon operation plate(30) having an inlet(36) at the bottom in the vicinity of the water reservoir side of the water gate and fixing two sides of the bottom to support structures(1) and fixing many T-shaped spacers(34) to the opposite side of the water gate of the siphon operation plate evenly, thereby discharging bottom water of the water reservoir side as much as the quantity of inflow water through a siphon passage(32) formed in a space between the water gate and the siphon operation plate.</p> |
