WATER TREATING METHOD, WATER TREATING APPARATUS, AND HYDROPONIC SYSTEM USING THE SAME

摘要

There is provided a method for water treatment, capable of greatly improving the effect of removing microbes contained in water for eating and drinking, or discharged water. This water treatment method comprises: a first treatment step of dipping a pair of electrodes and a conductor capable of collecting at least microbes in a running channel of water to be treated, and applying a positive potential to the conductor and applying negative potentials to the electrodes to adsorb the microbes on the conductor; a second treatment step of stopping the flow of the water to be treated after an end of the first treatment step, and increasing the potentials applied to the conductor and the electrodes to start the electrolysis of the water to be treated while the polarities of the potentials applied to the conductor and the electrodes are maintained intact in the presence of the water to be treated; and a third treatment step of stopping the application of the potential to the conductor after an end of the second treatment step, and applying a positive potential to one of the pair of electrodes and applying a negative potential to the other of the electrodes in the presence of the water to be treated.
