Abstract
Effect of gradational inflow or step-feeding is tested through experiments in a horizontal subsurface flow pilot-scale constructed wetland. The unit is a 3 m long and 0.75 m wide metal tank containing cobbles, where the vegetation (common reed) is planted. Experiments lasted from February 2007 to February 2008. Water samples were collected at the inflow, two intermediate points and the outflow of the system, and were analyzed in the laboratory for BOD, COD, nitrogen and phosphorus concentrations. A comparison was made for removals under various step-feeding schemes, including feeding only at the inflow. Results show that step-feeding application had a positive effect on wetland performance, since removal rates of most constituents were increased.
