Constructed wetland systems for treatment of wastewater from rural aeries could be an interesting alternative for conventional wastewater treatment plant. The objective of this paper was to evaluate the performance and efficiency of organic pollutants removal of hybrid constructed wetlands in the Gdańsk region working in temperate climate and under different loadings. Facility consisting of septic tank and vegetated subsurface bed (willow or reed) could be recommended for treatment of wastewater in rural areas. Hybrid Constructed Wetland (HCW) provides efficient and stable both organic matter and nitrogen removal with the efficiency up to 95.7% of BOD5 and 78.0 % of NTot. It was indicated that mass removal rates (MRRs) of organic matter (BOD,COD) for analysed HCW were independent of applied configuration in contrast to the MRRs of total nitrogen. The highest MRR of nitrogen (1.06 gNm-2day-1) was observed for vertical flow beds in Wiklino facility with unit area of 4.0 m2pe-1. There is a farther need to explain the main processes responsible for nitrogen removal and relationship between discharging loads and configurations of hybrid constructed wetlands.

Oczyszczalnie hydrofotowe mogą stanowić interesującą alternatywę dla konwencjonalnych rozwiązań gospodarki ściekowej na terenach o rozproszonej zabudowie. Celem pracy była ocena działania i skuteczności usuwania zanieczyszczeń w hybrydowych systemach hydrofitowych pracujących w rejonie Gdańska, w klimacie umiarkowanym. Technologiczne rozwiązanie składające się z osadnika gnilnego oraz złoża hydrofitowego z podpowierzchniowym przepływem ścieków może być zalecane do oczyszczania ścieków bytowo- gospo- darczych powstających na terenach wiejskich. Hybrydowe systemy hydrofitowe (HSH) zapewniają efektywne i stabilne w czasie usuwanie zarówno substancji organicznej (95.7%) jak i azotu ogólnego (78.0%). Wykazano, że wydajność usuwania substancji organicznej z 1m2 złoża nie zależała od konfiguracji systemu, podczas gdy wydajności usuwania azotu uzależniona była od zastosowanej konfiguracji. Największą wydajnością usuwania azotu charakteryzował się obiekt w Wiklinie (1.06 gNm-2d-1) w którym kwatery zraża pionowego (2.0 m2M-1) zasilane były ściekami okresowo.
