To reduce non-point source pollutants in Juam Lake eco-wetlands, purification efficiencies of pollutants were investigated at three different systems. The constructed wetlands (CWs) consisted of A system, B system and C system. A system consisted of free water surface (FWS) CW, FWS CW, FWS CW, subsurface flow (SSF) CW and SSF CW. B system consisted of FWS CW, FWS CW, FWS CW, FWS CW and SSF CW. C system consisted of FWS CW, FWS CW, FWS CW, FWS CW and SSF CW. The concentrations of BOD, COD, SS, T-N and T-P in inflow ranged 0.20 ~ 0.91, 1.24 ~ 8.00, 0.60 ~ 8.60, 0.04 ~ 2.50 and from March to October in 2011, respectively. Removal rates of BOD, SS, T-N and T-P were high in Autumn, Spring, Spring and Summer, respectively. In A system, FWS CW, FWS CW and FWS CW were dominated by Leersia oryzoides. In B system, FWS CW, FWS CW and FWS CW were dominated by Leersia oryzoides. In C system, FWS CW and FWS CW were dominated by Nymphaea teragona.
