WATER PURIFYING APPARATUS

PURPOSE:To maintain the life of ultraviolet ray sterilizing lamp and to treat the whole water to be treated efficiently and uniformly by providing jetting openings of water to be treated and ozone between plural rows of ultraviolet ray sterilizing lamps, providing a filtration vessel in which filter medium is piled up, and circulating the water to be treated and ozone by a pump. CONSTITUTION:Numbers of ultraviolet ray sterilizing lamps 3 are disposed in plural rows with a specified distance between rows, and jetting openings of water to be treated and ozone are provided between them, so that water is difficult to reach jackets 2 and ultraviolet ray sterilizing lamps 3 even when the water is vigorously jetted, so that the vibration of ultraviolet ray sterilizing lamps 3 is small and the life of ultraviolet ray sterilizing lamp 3 is maintained and the damage on the jackets 2 is eliminated. As the water contg. ozone is strongly energized, the whole water to be treated is efficiently and uniformly treated. The dust in the water is physically removed by the filter medium 7, and the noise transmitted to the outside is small because a pump 5 is situated in the water.
