<p>PURPOSE:To purify effectively discharged water from a large volume water area in the same process as the purification of a small volume water area by dividing part of a large volume dam by means of running water separation method and carrying out purification of the water in the divided area by means of the aeration purification process. CONSTITUTION:Lifting cylinders 3, 3a and 3b are provided close to an intake weir 2 of a large volume dam 1, outside of which a dividing water layer 4 is provided. In order to form said dividing water tank 4, a lower section water pipe 8 with a water absorption tank 7 is installed in parallel at a lower section of an upper section water pipe 6 with a slit 5. Then, the water is fluidized through a circulating water pipe 11 by starting a pump 14 transferred to the water pipe 6, blown downwardly out of the slit 5, and absorbed from an absorption channel 7 of a water pipe 8 to form a water layer 4 between the water pipes 6 and 8. In other words, diffused water from the lifting cylinder 3 is changed in its direction along said water layer 4, and the water between the dividing water layer 4 and an intake weir 2 can be purified effectively.</p> |
