A device is proposed for the UV disinfection of liquids in an open or closed channel (1), having an inflow for the liquid to be disinfected, at least one UV irradiator (2) arranged downstream of the inflow in a main flow direction (9), and also having an outflow arranged downstream of the UV irradiator (2), in which a mixing device (6, 12, 13, 14, 18, 21) which is driven by an electric motor is arranged between the inflow and the at least one UV irradiator (2), which mixing device is set up for generating a crossflow (8, 8') having at least one velocity component transverse to the main flow direction (9) in order to improve mixing of the liquid.
L'invention concerne un dispositif de désinfection de liquides par UV dans une rigole (1) ouverte ou fermée, qui présente une amenée pour le liquide à désinfecter, au moins un émetteur d'UV (2) disposé en aval de l'amenée dans la direction principale d'écoulement (9) ainsi qu'une évacuation disposée en aval de l'émetteur d'UV (2). Entre l'amenée et le ou les émetteurs UV (2) est disposé un dispositif de mélange (6, 12, 13, 14, 18, 21) entraîné par un moteur électrique et conçu pour créer un écoulement transversal (8, 8') dont au moins une composante de vitesse est transversale par rapport à la direction principale d'écoulement (9), pour améliorer le mélange du liquide.
