FIELD: chemistry. ^ SUBSTANCE: invention relates to water treatment technology and can be used for ozone treatment of drinking water in centralised water supply systems. The device has an ozone gas mixture generator, a reservoir with a water supply system and a system for discharging water to the consumer, in the near-bottom part of which are fitted gas dispersing elements, connected by pipes with the ozone gas mixture generator. The gas dispersing elements are in form of hollow two-layered panels with a uniformly perforated top layer, uniformly fitted on the cross section of the reservoir and forming a bouble bottom and double bottom space - a high pressure zone between the bottom layer of the panels and the bottom of the reservoir. The gas dispersing elements are fitted with centres for swirling the water stream in form of slot-type swirl atomisers, inlet openings of which are linked with the double bottom space, outlet slot nozzles are placed above the perforated surface of gas-permeable elements and are parallel the said surface. The double bottom space is linked with the system for supplying water to the reservoir. One face of the panels is placed on corner hinged bearings, and the ozone gas mixture pipes are the axis of rotation of the corner hinged bearings of the gas dispersing elements. ^ EFFECT: proposed invention increases mass-transfer surface between water and the ozone gas mixture; also reduces operating costs by cutting time for decontaminating the reservoir. ^ 2 cl, 6 dwg |
