- Abstract
The aim of this study was to evaluate the behavior of constructed wetlands with aquatic macrophytes in decreasing the concentration of pollutants from urban effluents. A pilot-scale system with two coverages of floating plants and two hydraulic residence times, working with continuous flow laminar was built. The lower concentration of chemical oxygen demand and biological oxygen demand, were obtained with the lower coverage and higher hydraulic residence times. With little influence of the variables on the concentration of total nitrogen and total suspended solids, being the significant response for total phosphorus with the lowest plant coverage. There was a highly significant removal of total coliforms, regardless of coverage and in favor of higher hydraulic residence times. The use of free water surface wetlands is auspicious for sanitary control, showing low incidence on total nitrogen and total phosphorus.
