More Information
Summary:A water treating apparatus for treating water, includes: an oil drop separator for separating oil drops from water to be treated which has an electrode in which an anode is made of amphoteric metal, a power source for supplying an electric power to the electrode, a treating tank for housing the electrode and the water, a water inlet through which the water is led to the treating tank, and a water outlet through which the treated water is exhausted from the treating tank; and a three-dimensional fixed bed type electrolytic tank for treating the water which has been treated by the oil drop separator which has a fixed bed type electrode, a power source for supplying an electric power in which a polarity is reversed periodically, to the fixed bed type electrode, a treating tank for housing the fixed bed type electrode and the water, a water inlet through which the water is led to the treating tank, and a water outlet through which the treated water is exhausted from the treating tank. The apparatus further includes leading device for leading the water exhausted from the water outlet of the oil drop separator to the water inlet of the three-dimensional fixed bed type electrolytic tank.
