<p>PROBLEM TO BE SOLVED: To provide a liq. purification and sterilization apparatus with high purification and sterilization force which can keep the photochem. reaction effect processed by a photocatalyst for a long time. SOLUTION: Bath water stored in a bathtub is fed into a microorganism filtering tank by means of a circuration pump 64 and the bath water is purified in the microorganism filtering tank and is electrolyzed in an electrolytic tank 12 and, by feeding oxygen gas and acidic bath water formed on the anode 12 side of the electrolytic tank 12 into a photocatalytlc tank 18, oxygen gas included in the acidic bath water accelerates photochem. reaction in the photocatalytic tank 18 and the sterilization force is improved.</p> |
