ELECTRIC FIELD TREATMENT APPARATUS AND TREATMENT METHOD

摘要

A water treatment apparatus (10) as an electric field treatment apparatus comprises a cylindrical bottomed tank (15) for containing water, an outer electrode (17) applied to the inner circumferential surface (15A) of the tank (15), a cylindrical central column (18) arranged in the central part of the tank (15), and an inner electrode (19) applied to the outer circumferential surface (18A) of the central column (18). The space between the outer electrode (17) and the inner electrode (19) serves as an electric field treatment area E for treating water with electric field. AC voltages of the same polarity are applied to the electrodes (17, 19) so that a plus electric field and a minus electric field are alternately generated in the electric field treatment area E.
