NOVELTY - An integrated solar photo-electrical water treatment device comprises set(s) of solar battery assembly and corresponding controller; accumulator set(s); set(s) of optical electrode and electrode pair or three-dimensional electrode; UV lamp(s); and at least one electrolytic bath. The optical electrode and electrode pair are placed in electrolytic bath correspondingly. The electrolytic bath has water inlet and water outlet. The optical electrode is active optical electrode catalyzed by UV light and/or visible light.    USE - Integrated solar photoelectrical device for water treatment.    ADVANTAGE - The device integrates optical chemical oxidation with electrochemical oxidation process, both can produce enhancing and synergy action to improve water treatment efficiency, and the device can perform function of the optical chemical oxidation or electrochemical oxidation singly to realize water purification. The device has simple structure, low production cost and simple and safe operation, can easily realize automation and safe maintenance, and can partially or totally utilize electric energy converted by solar energy to drive the whole water treatment process, which solves the problem that the photoelectrical catalysis water treatment process depends on energy highly. The device will not depend on the existing electric net in operation.    DETAILED DESCRIPTION - An integrated solar photo-electrical water treatment device comprises set(s) of solar battery assembly and corresponding controller; accumulator set(s); set(s) of optical electrode and electrode pair or three-dimensional electrode; UV lamp(s); and at least one electrolytic bath. The optical electrode and electrode pair are placed in electrolytic bath correspondingly. The electrolytic bath has water inlet and water outlet. The optical electrode is active optical electrode catalyzed by UV light and/or visible light. The UV lamp is used for irradiating the optical electrode. The solar battery assembly is used for converting the received solar energy into electric energy, and then conveying and storing in accumulator set, and intermittently or continuously supplying power to UV lamp and/or electrode pair.    DESCRIPTION OF DRAWING(S) - The drawing is a perspective view of an integrated solar photoelectrical water treatment device.
