The wastewater treatment system have a plurality of treatment modules. Influent is directed to a fixed film reactor (13). The water then flows to a hydroponic reactor (19) in which aquatic plants are suspended atop the liquid. A filtration device (28) in the form of a vertical flow wetland removes suspended solids. Water may be recycled to the fixed film reactor to enhance nitrogen removal.
L'invention concerne un système de traitement d'eaux usées comportant une pluralité de modules de traitement. Un influent est dirigé en direction d'un réacteur à couche fixe (13), les eaux s'écoulant ensuite en direction d'un réacteur hydroponique (19) dans lequel des plantes aquatiques sont en suspension en haut du liquide. Un dispositif de filtration (28) se présentant sous forme de zone humique à flux vertical élimine les solides en suspension. De l'eau peut être envoyée au réacteur à couche fixe afin de renforcer l'élimination d'azote.
