Abstract
L'invention concerne l'épuration des eaux résiduaires. Une installation pour le traitement d'eaux usées, avec une pluralité de compartiments de stabilisation entre lesquels sont intercalés des coudes, des dispositifs d'aération étant placés dans les coudes, est caractérisée par le fait que les compartiments 3 de stabilisation comportent, dans le domaine des coudes 6 équipés de dispositifs 7 d'aération, des couvercles 8 pour les chambres d'oxydation 9 d'un dispositif de gazéification 10 par l'oxygène, lesdites chambres d'oxydation 9 étant placées les unes derrière les autres en tant qu'étapes en cascade du dispositif de gazéification 10 par l'oxygène. Application à l'élévation de la capacité de traitement de telles installations.
