IPC: C02F1/463
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To remove impurities as high as a desired purification level in a short period of time by the polarization functions due to the action of electric field by providing the device with a treatment tank of closed construction having on its upper and lower ends an anode and a cathode, and an inlet and outlet ports for waste water, respectively, and disposing a dielectric plate horizontally in the tank so as not to come into contact with the anode and cathode. SOLUTION: Liquid to be treated flows into a treatment tank 1 from its inlet port 8 and flows out from an outlet port 9 via an S-shaped passage. At that moment, in a space defined by a dielectric plate 4 in the tank 1, if a predetermined voltage is applied between a cathode 2 and an anode 3, an electric field of a predetermined intensity is generated between the cathode and anode so that the plate 4 is polarized by the polarization action and the flocculation of impurities is accelerated by the catalytic action of the plate 4 and at the same time, a positive surface of the plate 4 emits metal ions, while a negative surface thereof emits minus electrons. And small bubbles of hydrogen are combined with suspended matters so as to be separated by a suspended matter removal device so that the deposition of the suspended matters from the liquid to be treated can be accelerated.  And thereafter, the liquid to be treated is discharged from the tank 1 through a pipe on the side of the outlet port 9.
