<P>PROBLEM TO BE SOLVED: To dispense with a pump for bubble atomizing operation, and to stably supply ozone microbubbles at a low cost. Ž<P>SOLUTION: A water treatment apparatus includes microbubble generators 10-13 for introducing ozone-containing gas to generate microbubbles in water to be treated in an ozone tank, a flowmeter 19 for measuring the flow rate of the water to be treated, a water quality meter 20 for measuring the water quality of the water to be treated, and a controller 21 for carrying out ozone treatment of the water to be treated from the measured values of the flowmeter or the water quality meter. The microbubble generator includes a bubble injection portion formed in a hollow disk shape and bored with a plurality of bubble injection holes, and a rotating shaft for receiving turning force of a motor to rotate the bubble injection portion. The bubbles generated from the bubble injection holes are torn by shearing force generated by rotating the bubble injection portion to generate the fine bubbles of the ozone-containing gas in the ozone tank. The controller 21 carries out at least one of the revolution number control of the bubble injection portion and the flow rate control of the ozone-containing gas according to the measured values of the flowmeter 19 or the water quality meter 20.
