Claim Text:
1. An apparatus for generating fine bubbles having positive charges, comprising: an electrolysis bath having an anode plate and a cathode plate in an interior space, into which a predetermined amount of treated water is supplied, to electrolyze the treated water, wherein the anode plate is formed of iron or aluminum, and wherein the electrolyzed treated water is positively charged by iron ions or aluminum ions produced from the anode plate; and a mixing tank, to which the electrolyzed treated water is supplied in a pressurized state by a pump disposed at an intermediate portion of a water feeding pipe extending from the electrolysis bath, and to which air is supplied through an air inflow control valve, the mixing tank being provided therein with a plurality of nozzle blocks separated at constant intervals from each other on an inner surface of the mixing tank, and at least one nozzle hole is formed through each of the nozzle blocks such that a mixture of the treated water and the air passes through the nozzle holes to form fine bubbles, wherein the treated water is discharged together with the fine bubbles having positive charges generated during electrolysis through an outlet of the mixing tank; and adjacent nozzle blocks of the plurality of nozzle blocks have the at least one nozzle hole formed therethrough in positions that are offset from one another; and wherein adjacent nozzle blocks of the plurality of nozzle blocks have differing numbers of the at least one nozzle holes formed therethrough.
