Abstract: Electric power energy required in an alkaline water electrolytic device and an alkaline fuel cell for continuing an electrolytic treatment, a hydrogen gas and an oxygen gas serving as raw materials for the electric power energy, an amount of water corresponding to raw water lost through the electrolytic treatment, and an electrolytic solution are efficiently circulated and used in a water treatment system to considerably reduce electric power consumption. Provided is a water treatment system using an alkaline water electrolytic device and an alkaline fuel cell in which an alkaline water electrolytic device and an alkaline fuel cell are connected to each other, the volume of raw water is reduced, an oxygen gas and a hydrogen gas that are generated from the alkaline water electrolytic device are fed to the alkaline fuel cell, the oxygen gas and hydrogen gas are used to generate electric power by the alkaline fuel cell, electric energy and water are collected, and the collected electric energy is fed to the alkaline water electrolytic device as an electric power source thereof.
