Apparatus and method for purifying water of farming and fish-farming ponds

摘要

PURPOSE: To recover self purification capacity of fish farm by feeding microorganisms having high nutrient removal efficiency into fish farm while fine air bubbles being supplied into fish farm evenly at upper and lower part thereof, thereby improving water quality of fish farm. CONSTITUTION: The system comprises a fish farm(11); a complex sensor part(12) measuring the water quality of the fish farm and outputting the measured results; a control part(13) processing the water quality data and controlling the system wholly; a fine bubble generator(14) which generates fine air bubbles to supply it to the fish farm; a microorganism storage tank(15); a water current generator(16) equally diffusing the air bubbles and microorganisms from the fine bubble generator and microorganism storage tank to the lower part and the upper part of the fish farm; and a multilayer filter(17) discharging the contaminants of the fish farm to the outside.
