The aim of this study was to investigate the treatment efficiency of passive vertical-flow constructed wetland filters containing different macrophytes (Phragmites and/or Typha) and granular media with different adsorption capacities. Different concentrations of lead and copper sulphate were added to the polluted urban stream inflow water to simulate pre-treated mine wastewater. A fertilizer was added to one filter only. The relationships between growth media and plant communities as well as the reduction of predominantly lead and copper were investigated. Lead, copper and 5-day biochemical oxygen demand (BOD) concentrations were reduced similarly for all the wetlands. An analysis of variance showed that the concentration reductions (mg/l) of lead, copper and BOD were significantly similar for the six experimental wetlands. There appears to be no additional benefit in using expensive adsorption media like granular activated carbon to enhance biomass performance during the first 10 months of operation.
