<p>A water treatment method and a water treatment apparatus capable of remarkably improving the effect of removing the bacteria from drinking water or drainage, and a water culture system using the method and the apparatus. The water treatment method comprises a first treating step of submerging an electrode and carbon fibers capable of collecting at least bacteria in a channel of water to be treated, applying a positive potential to the carbon fibers, and applying a negative potential to the electrode to adsorb bacteria onto the carbon fibers, a second treatment step of stopping the flow of the water after the first treating step, and raising the potentials applied to the carbon fibers and the electrode while keeping the polarities of the potentials to cause the electrolysis of the water, and a third treating step of applying, after the second treating step, an AC voltage between the electrode and the carbon fibers in the presence of the water.</p> |
