Grauwasserreinigung mit einer Sumpfpflanzenmatte unter Praxisbedingungen

Abstract: Die dezentrale Behandlung von Grauwasser findet weltweit immer größere Beachtung. Da in der Regel ebenerdige Flächen kostenintensiv sind, kann alternativ die Grauwasserbehandlung mithilfe von Sumpfpflanzenmatten auf Gebäudedächern erfolgen. Neben der Wasserbehandlung wirkt sich dieses Vorgehen positiv auf die Gebäudeklimatisierung aus. In einem Test unter Praxisbedingungen konnte gezeigt werden, dass eine Sumpfpflanzenmatte mit 0,1 m Wurzelschichthöhe bei hydraulischen Flächenbelastungen bis 15 L m -2 d -1 für… Show more

“…As well as treating water, this process also has a positive effect on climate regulation inside buildings [23][24][25]. In a test carried out under realistic conditions, it was shown with the aid of a pilot plant that a helophyte mat with a root-layer thickness of 0.1 m is capable of treating typical greywater from a residential building during the growing season at hydraulic loads per unit area of up to 15 L/m 2 × d [26][27][28]. Zapater-Pereyra et al found that a constructed wetland roof was capable of meeting up to the strictest treatment level (60 mg L −1 fortotal suspended solids (TSS), 40 mg L −1 for 5-day biochemical oxygen demand (BOD 5 ), 200 mg L −1 for chemical oxygen demand (COD), 4 mg L −1 for NH 4 + -N, 60 mg L −1 for total nitrogen (TN), and 6 mg L −1 for total phosphorus (TP)) required by Netherlands guidelines for discharge into water bodies given that the overflow water was directed to an infiltration pond [9].…”

“…zur Grauwasserbehandlung zeigten eine gute Reinigungsleistung. Allerdings bilden diese Pflanzen ein sehr feines Wurzelgeflecht aus, wodurch der Wurzelraum die Durchströmung des Wassers stark beeinträchtigt . Um höhere Abwasservolumenströme realisieren zu können, wurden deshalb weitere Sumpfpflanzen in Betracht gezogen (Abb.…”
