Abstract

L'invention concerne une installation de traitement d'eaux usées où le processus de traitement biologique des eaux usées est précédé d'une étape de déphosphatation (1) et où, dans une première étape, le procédé s'effectue progressivement au moyen d'un processus de nitrification (2), étape à partir de laquelle se produit un écoulement, le débit d'écoulement est égale au débit d'entrée des eaux usées, jusqu'à un débit de dénitrification (3), et la quantité d'eaux usées qui s'écoule est la quantité d'eaux usées traitées, l'écoulement sortant étant dirigé vers des bassins de décantation secondaires (5) à travers une chambre de collecte (4). L'installation de traitement comprend un réservoir (8) constituant un débit supplémentaire relié au débit de l'installation de traitement d'eaux usées effectuant la nitrification (2) et la dénitrification (3), le réservoir provoquant un changement contrôlé en continu de la capacité des eaux usées soumises à une nitrification (2) et/ou une dénitrification (3), afin d'augmenter l'efficacité de l'ensemble du dispositif de traitement.
