AQUEOUS MEDIUM PURIFYING AND DISINFECTING APPARATUS Russian patent published in 2001 - IPC

FIELD: sewage purifying and disinfecting equipment. SUBSTANCE: apparatus has circulation circuit including jet pump with ejector and circulation circuit cavitation chambers, photochemical reactor and filter. Apparatus is equipped with device for producing electrically activated water with anolyte and catholyte chambers, coagulation chamber and catholyte cavitation chamber. Cavitation chamber is joined to photochemical reactor and has at least one supersonic emitter and at least one ultraviolet emitter. Outlet of anolyte chamber of device for producing electrically activated water is connected via anolyte cavitation chamber to cavitation chamber. Circulation circuit positioned in front of filter includes coagulation chamber. Jet pump with ejector is connected to outlet end of catholyte chamber of device for producing electrically activated water. Catholyte cavitation chamber is used as cavitation chamber of circulation circuit. Apparatus is further provided with unit for producing and supplying of ozone-containing mixture. This unit is joined to air supplying unit of cavitation chamber and/or anolyte cavitation chamber, and/or jet pump. Apparatus is used for purifying and disinfecting of industrial or domestic sewage, of surface water sources from contaminants of different kind and nature by multistaged in-flow treatment of aqueous media. EFFECT: increased efficiency in removal of organic, inorganic, toxic contaminants and pathogenic microflora. 2 cl, 1 dwg
