ENVIRONMENT-FRIENDLY CONSTRUCTION METHOD FOR PURIFYING POLLUTED RIVER WATER USING A WATER STORAGE SYSTEM FOR DISCHARGING CLEAN RIVER WATER OF HEAVY SPECIFIC GRAVITY PREFERENTIALLY THROUGH THE BOTTOM OF A WATER GATE AND A WATER PURIFICATION SYSTEM FOR PURIFYING POLLUTED RIVER WATER THEREFOR

摘要

PURPOSE: An environment-friendly construction method for purifying polluted river water using a water storage system for discharging clean river water of heavy specific gravity preferentially and a water purification system for purifying polluted river water therefor are provided to purify polluted river water naturally by explosion of materials and friction of materials caused when polluted river water of light specific gravity meets river water of heavy specific gravity. CONSTITUTION: An environment-friendly construction method for purifying polluted river water using a water storage system for discharging clean river water of heavy specific gravity preferentially comprises the steps of: forming a water gate(1) to a concrete foundation(6) by a hinge; coupling a bottom water discharge passage(2) to the inside of the water gate by a steel plate(3) to discharge bottom water of heavy specific gravity automatically with the influence of gravity; forming a gravity dispersion device(4) on the bottom of the steel plate; forming a ∩v-shaped cover(9) on the upper part of the bottom water discharge passage to prevent impurities like garbage or the branches of a tree discharged through the upper part of the bottom water discharge passage from flowing in a vortex generation passage; forming an influent water cutoff plate to the bottom of the bottom water discharge passage by a hinge; and forming a vortex generating passage(8) and a vortex generating plate on the backside of the water gate.
