<p>The present invention is about the purification method of a polluted river using a multiple stage discharge system consisting of aeration-causing water gates which operate either by water pressure or water power. Motor power transmitting systems are connected to the aeration-causing water gates and then a central control system controlling those motor power transmitting systems is constructed. Then, the opening, closing and the patterns of each of the aeration-causing water can be controlled and so water purification can be done in a more aggressive manner.</p> |
