摘要：
The wastewater treatment systems have a plurality of treatment modules between the inlet and the outlet, each for treating water with a selected process. Influent is directed to a fixed-film reactor. Water then flows to a hydroponic reactor, in which aquatic plants are suspended atop the liquid for achieving aquatic-root-zone treatment. A filtration device removes any remaining suspended solids following the hydroponic reactor. Recycling may occur to the fixed-film reactor to enhance nitrogen removal from one or both of the hydroponic reactor and the filtration device.
