ENVIRONMENTALLY-FRIENDLY METHOD FOR PURIFYING CONTAMINATED RIVER WATER AND AN ENVIRONMENTALLY-FRIENDLY WATER PURIFICATION SYSTEM APPLIED TO THE SAME FOR DISCHARGING HEAVY-PROPORTION CLEAN RIVER WATER THROUGH A BOTTOM WATER OUTLET WHICH NATURALLY PURIFIES CONTAMINATED RIVER WATER AND SEPARATELY DISCHARGING THE CONTAMINATED RIVER WATER THROUGH TWO INLETS AND FOUR OUTLETS USING GRAVITY FOR AUTOMATICALLY SEPARATING THE CONTAMINATED RIVER WATER BY MATERIAL MOLECULES

摘要

PURPOSE: An environmentally-friendly method for purifying contaminated river water and an environmentally-friendly water purification system are provided to regularly maintain a river water quantity by preventing the river water from being discharged through the bottom water outlet of a floodgate at once in the dry season.;CONSTITUTION: An environmentally-friendly method for purifying contaminated river water comprises the following steps: primarily discharging river water to the upper part of a multifunctional movable floodgate(80); purifying the overflowing river water through material friction and aeration effects by falling to the upper end of a shoal generating plate(50); preferentially discharging heavy-proportion clean river water in a water storage space lower part along with contaminants to improve water quality; and simultaneously discharging the river water at the same amount as an upstream inflow through the lower end of the multifunctional movable floodgate and preventing water-bloom by raising the river water to the upper part without stagnating.;COPYRIGHT KIPO 2013
