WATER TREATMENT APPARATUS

PURPOSE:To enable effective decomposition by oxidation of org. compds. contained in the water, sterilization of general bacteria and colibacillus, and removal by decomposition of residual chlorine by circulating water through a space between a cylindrical water passage and an ultraviolet ray source and between the space and a water storage tank. CONSTITUTION:A cylindrical water passage 16 is provided to an upper half part of a main body 15 of the apparatus, and an ultraviolet ray source 14 is installed to an internal hollow part of the water passage 16, simultaneously. Further, a water storage tank 17 is formed at the bottom of the water passage 16, and water is circulated through a space between the water passage 16 and the ultraviolet ray source 14 and in the water storage tank 17. Thus, the falling water around the ultraviolet ray source 14 is irradiated with ultraviolet rays, and ozonized gas is mxied with the falling water around the ultraviolet ray souce 14 effectively by repeating contact several times. As the result, oxidative decomposition of org. compds. contained in the water, sterilization of general bacteria and colibacillus, and removal and deodorization of residual chlorine is accomplished effectively.
