Abstract

L’invention concerne un dispositif (1) de traitement des eaux usées par filtre planté de végétaux de préférence du type roseaux, comportant au moins un premier étage (FP1) de filtre planté comprenant une pluralité de couches filtrantes à base de substrat minéral dont une couche supérieure de type gravier fin, destinée à accueillir les végétaux, une couche de transition juste en-dessous de la couche supérieure et du type constituée de graviers filtrants plutôt fins de granulométrie plus étendue que celle de la couche supérieure, et au moins une couche de fond dite drainante du type à graviers grossiers, caractérisé en ce qu'il comporte en outre, en amont dudit filtre, au moins un premier ouvrage d’alimentation (20) de type chasse ou poste en forme de cuve de stockage équipé d’un dispositif totalement immergé (100) d’injection de microbulles d’air créant une aération et un brassage des eaux usées permettant une suroxygénation avant leur passage dans le premier étage (FP1) de filtre planté et d’un dispositif d’injection de bactéries nitrifiantes et/ou déphosphatantes constituant un réacteur biologique de traitement préliminaire.
