Definitions
- the wastewater after the recovery unit via a treatment unit in which a reactive gas passed into the wastewater and / or the wastewater is treated with UV Strahiung is led into a KSarwasserfr hope. Since the wastewater contains hardly any solids, the use of the treatment unit is very efficient, so that, in some cases, even a treatment residue prior to the recovery unit can be dispensed with.

Abstract
L'invention porte sur un dispositif de traitement des eaux résiduaires d'une machine (6) servant à la fabrication d'une bande de papier, de carton, de papier mousseline ou d'une autre matière fibreuse, à partir d'une suspension de matières fibreuses, les matières solides étant séparées des eaux résiduaires dans une unité de récupération (2). L'objet de la présente invention est de diminuer la formation de mucilage, de manière aussi simple que possible. A cet effet, en amont de l'unité de récupération (2), les eaux résiduaires sont envoyées dans une unité de traitement (1) dans laquelle un gaz réactif est introduit dans les eaux résiduaires, et/ou les eaux résiduaires sont traitées par rayonnement UV.
