An environment-friendly method for purifying contaminated river water using a sluice is provided to preferentially discharge lower water of a reservoir through a discharging path when a water gate is stood up, thereby naturally purifying polluted water. An environment-friendly method for purifying contaminated river water comprises a water gate(20) and an operating link(31). The water gate is inclined toward a drainer to be put under pressure generated by water pressure and weight of the water gate. The operating links are respectively connected to be rotated by a driving unit on both lower sides of the water gate. The water gate opens or closes a water path according to rotation of the operating link. |
