<p>The present invention discloses a water purification apparatus for purifying the water in a reservoir such as a fish farm, a fishing place, a pond, a submerged weir, etc. The water purification apparatus of the present invention comprises a contaminated water discharge means installed on the bottom of a reservoir, compulsorily discharging the contaminated water including precipitates to the outside; a precipitate filtration means filtering the contaminated water discharged to the outside by the contaminated water discharge means to filter out the precipitates; a transfer pipe consisting of a contaminated water transfer pipe to transfer the contaminated water discharged from the contaminated water discharge means to the precipitate filtration means and a purified water transfer pipe to retransfer the water purified in the precipitate filtration means to the reservoir; and a control means to control the driving of the contaminated water discharge means. The water purification apparatus of the present invention is installed in a reservoir where a great quantity of water is stored, simply discharges the precipitates on the bottom of the reservoir to the outside of the water while completely removing the contaminants (precipitates) in the water, and increases the level of dissolved oxygen, thereby always keeping the reserved water clear and pure.</p> |
