DEVICE FOR OZONISING WATER AND METHOD FOR OZONISING WATER

The invention relates to water treatment by ozonising and can be used, in particular for disinfecting drinking water in water supply systems. The inventive device for ozonising water comprises an air preparation system connected to at least one ozone generator provided with a power supply, a reactor pot embodied in the form of a hermetic contact basin. At least one dispersant embodied in the form of a porous plate having the pore dimensions ranging from 10 to 150 mkm or a plate provided with channels having frustaconical shape whose diameters at the input and the output of ozone are equal to 180-200 mkm and 100-150 mkm, respectively. Said device is also provided with a system for treating residual ozone embodied in the form of at least one block of nozzles connected to a source of atomised water and arranged above the surface of the treated water in such a way that said treated water is completely covered by the atomised water. The elements of the device are mainly united into separate container type modules. The inventive method for ozonising water carried out with the aid of the inventive device is also disclosed. In order to increase the degree of ozone utilisation, the inventive device is provided with an additional system for treating the residual ozone embodied in the form of an additional contact basin which water input is connected to the water output of the main contact basin, the water output of the additional contact basin being connected to the water input of the main contact basin. Said invention improves the efficiency and quality of water treatment by increasing the degree of ozone utilisation. L'invention concerne des techniques de traitement de l'eau par ozonisation et peut s'utiliser notamment pour la désinfection de l'eau dans des systèmes d'alimentation en eau. L'installation d'ozonisation d'eau comprend un système de conditionnement d'air relié avec au moins un générateur d'ozone muni d'une source d'alimentation électrique, une cuve de réaction se présentant comme un bassin de contact à l'intérieur duquel est monté au moins un disperseur ayant la forme d'une plaque poreuse, la taille des pores étant de 10 à 150 micromètres, ou d'une plaque comprenant des canaux ayant une forme tronconique dont le diamètre à l'entrée et à la sortie d'ozone est de 180 - 200 micromètres et 100 - 150 micromètres, respectivement. L'installation comprend aussi un système de traitement de l'ozone résiduel qui se présente comme au moins une unité de buses reli
