Document Type and Number:
Japanese Patent JP4142811
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus keeping the balance of an ecosystem of the whole of a plankton phase and accelerating the generation of plankton other than that of the genus Microcystis while suppressing the generation of plankton of the genus Microcystis. SOLUTION: In a water area having a high pH region containing plankton and a low pH region, which contains phosphate ions, formed under the high pH region, acidic electrolytic water obtained on an anode side by electrolysis is added to the high pH region and alkaline electrolytic water obtained on a cathode side by electrolysis is added to the low pH region to lower the concn. of plankton in water. A cleaning apparatus of water containing plankton is constituted of an electrolytic cell 1 equipped with an anode chamber 5 provided with an anode 7 and a cathode chamber 6 provided with a cathode 8, the acidic electrolytic water outflow pipe 13 connected to the anode chamber 5, the alkaline electrolytic water outflow pipe 14 connected to the cathode chamber 6 and the branch pipes 16 of a water collecting pipe 15 connected to the anode chamber 5 and cathode chamber 6 of the electrolytic cell.
