TREATING DEVICE AND TREATING METHOD FOR IONIC SUBSTANCE- CONTAINING WATER USING ACTIVATED CARBON ELECTRODE AND REGENERATING METHOD OF ACTIVATED CARBON ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a method of treating an ionic substance-containing water using an activated carbon electrode which efficiently adsorbs ions which are included in water to be treated, conveniently and surely removes the ions which are adsorbed on electrodes and can regenerate the electrode, a regenerating method of the activated carbon electrode and a treating device for the ionic substance-containing water.;SOLUTION: Solid activated carbon electrodes 1, 2 are disposed in a treating water vessel 6 and releasing electrodes 3, 4 for having no ionic adsorbability are disposed on both outer sides of the solid activated carbon electrodes and, in the electric double layer adsorption treatment, a direct current power source 7 is connected with the solid activated carbon electrode. In the regeneration of the solid activated carbon electrodes which adsorb an ionic substance, the ionic substance is released by short- circuiting between the solid activated carbon electrodes (8c-8d), thereafter, a direct current power source is connected with the releasing electrodes so as to invert the polarity, furthermore, the ionic substance is moved from the solid activated carbon electrodes and the solid activated carbon electrodes are thus surely regenerated with a simple structure.;COPYRIGHT: (C)2002,JPO
