Problems solved by technology

[0003] Photocatalysts can be applied to water purification treatment, such as the treatment of various water sources, especially water storage tanks, kitchen water treatment, etc., which require a large amount of fast water treatment. Generally, household reverse osmosis purification machines are only suitable for drinking water, not suitable for water treatment. All domestic water is treated, in addition to the high cost of treatment, the equipment to achieve high water output is also very expensive
However, water treatment using the photocatalyst effect of nano-titanium dioxide has not been widely used at present, mainly because the ultraviolet light source device that makes the photocatalyst produce oxidation is still expensive equipment, such as the price of germicidal lamps, etc. is still high
Furthermore, up to now, most of the devices using photocatalysts have installed photocatalysts in the form of powder or granules on the filter, because the effect of photocatalysts in the absence of light is not good and the contact area is small, resulting in poor purification effect

Abstract

The invention provides a photocatalyst water purification device comprising at least one water channel, wherein at least one flexible sheet, at least one upper sealing substrate and at least one lower sealing substrate are mutually sealed to form the water channel. The thickness direction of the flexible sheet is vertical to the thickness directions of both the upper sealing substrate and the lower sealing substrate, so that a water flow space is formed. A photocatalyst film is formed on the flexible sheet in the water channel and is in contact with the water. At least one ultraviolet LED module is arranged on one or both of the upper and lower sealing substrates, so that the water on the photocatalyst film can be illuminated by the light emitted by the ultraviolet LED module.
