A wastewater treatment system (10) includes, in serial fluid communication, a first lagoon (11a), a first vertical flow marsh cell (12a), a second lagoon (11b), and a final marsh cell (12c). with process recycle from the final cell to the first lagoon. The lagoons function essentially aerobically, and both the lagoons and the marsh cells contain plant roots (20, 291) contacting incoming water. A tidal vertical flow system (10.Dot., 10.Dot.) has atleast three marsh cells (12a'-12c') in serial forward fluid communication, incoming wastewater channeled to at least the first two cells, and a portion of water exiting a final cell recycled. Each cell is alternately flooded and drained for enhancing aeration of incoming water and cell contents, cell media (27) and plant roots having biofilm growing thereon. The biofilms include a population of nitrifying and denitrifying bacteria, for achieving substantially simultaneous nitrification and denitrification of the wastewater.

L'invention concerne un système de traitement des eaux usées (10) comprenant en communication fluidique sérielle, une première lagune (11a), une première cellule de marais à écoulement vertical (12a), une seconde lagune (11b) et une cellule de marais finale (12c), un processus de recyclage allant de la cellule finale à la première lagune. Ces lagunes fonctionnent principalement de manière aérobique, et les lagunes et les cellules de marais contiennent des racines de végétaux (20, 91) en contact avec l'eau entrante. Un système à écoulement vertical de marée (10.Dot., 10.Dot.) présente au moins trois cellules de marais (12a'-12c') en communication fluidique avant sérielle, les eaux usées entrantes étant canalisées jusqu'à au moins les deux premières cellules et une partie de l'eau sortant d'une cellule finale sous forme recyclée. Chaque cellule est remplie de façon alternante et est drainée pour améliorer l'aération de l'eau entrante et les contenus des cellules, des milieux cellulaires (27) et des racines de végétaux présentant des biofilms en pleine croissance. Ces biofilms englobent une population de bactéries de nitrification et de dénitrification destinée à réaliser pratiquement simultanément la nitrification et la dénitrification des eaux usées.
