ENVIRONMENT-FRIENDLY CONSTRUCTION METHOD FOR PURIFYING POLLUTED RIVER WATER USING A WATER PURIFICATION SYSTEM FOR DILUTING HEAVY BOTTOM WATER AND LIGHT SURFACE WATER, AND A WATER PURIFICATION SYSTEM FOR PURIFYING THE POLLUTED RIVER WATER THEREFOR USING A BOTTOM WATER DISCHARGE PASSAGE, A VORTEX GENERATING PASSAGE AND AN INFLUENT WATER CUTOFF PLATE

摘要

PURPOSE: An environment-friendly construction method for purifying polluted river water using a water purification system for diluting heavy bottom water and light surface water, and a water purification system for purifying polluted river water therefor are provided to prevent a vortex generating passage from closing by adulterations like garbage and the branches of a tree, and to purify polluted river water naturally by the material explosion action and the material friction action caused when heavy clean river water and light polluted river water meet. ;CONSTITUTION: In a water purification system for purifying polluted river water used for an environment-friendly construction method for purifying polluted river water, a v-shaped cover(9) is formed on the top of a bottom water discharge passage to prevent the re-inflow of impurities like garbage discharged through the backside of a water gate to a vortex generating passage through the top of a bottom water discharge passage(7) of a water gate(1), and an influent water cutoff plate(5) and a stop bar(6), which prevents the influent water cutoff plate from falling backward, are formed on the bottom of the bottom water discharge passage, and a vortex generating passage(8) and a vortex generating plate(2) are formed on the backside of the water gate to discharge heavy bottom water flew inward through the bottom water discharge passage to the bottom of foundation concrete(10) through the backside of the water gate.;COPYRIGHT KIPO 2011
