FIELD: water treatment. SUBSTANCE: apparatus comprises casing 1, contact chamber 2, outlet pipe 3 for discharging treated water, ultraviolet lamp 4 enclosed in shell 5 made of material transparent for ultraviolet radiation, inlet pipe 6 for water supply and device 7 for dispersing ozone-air mixture. Ultraviolet lamp 4 is arranged coaxially with casing 1, while dispersing device 7 is disposed below ultraviolet lamp 4. Openings 8 are formed in wall of contact chamber 2 for admitting into it water to be ozonized. Ejector 9 is interposed between ultraviolet lamp 4 and dispersing device 7, coaxially to them. Ejector 9 has outlet opening 10 with diameter smaller than that shell 5 of ultraviolet lamp 4. Admission openings 8 in contact chamber 2 wall are positioned at such a level as is limited by height of ejector 9. EFFECT: high quality of thus-purified water. 1 dwg
