Treatment of Polluted River Water Using Surface Flow Constructed Wetlands in Xinyi River Floodplain

Abstract:

Treatment of polluted river water with great variations of water quality using pilot-scale Surface Flow Constructed Wetland (SFW) was studied in this paper. The main results show that: When the influent concentrations of COD_Mn and NH₄⁺-N were 11.69~60.00 mg•L^-1 and 1.37~20.18 mg•L^-1, the COD_Mn and NH₄⁺-N removal rate of SFW which planted Lythrum salicaria, Canna indica, Typha latifolia and Scirpus locustris were 26.44％、40.12％、46.71％、28.23％ and 64.27％、70.49％、66.78%、58.52%. Typha latifolia and Canna indica have stronger ability for purifying pollutants. Scirpus locustris has strongest ability of overhead flooding, it can resist inundation over 22 days and still live. Lythrum salicaria has lowest ability of overhead flooding, it only can resist inundation 7 days.
