Abstract
Azo dye is a recalcitrant pollutant and is difficult to degrade if present in wastewater. The complete degradation of dye is very difficult in various treatment systems such as constructed wetlands, activated sludge systems, anaerobic digestion, and absorption. A new approach based on a constructed wetland (CW) coupled with a microbial electrolysis cell (MEC) has been tested for this purpose. The experiment was performed on a laboratory scale in two microcosms: one microcosm was filled with normal gravel (Control-CW) while the other one was filled with graphite as a conductive material and connected to a solar panel (CW-MEC). Color and COD removal efficiency at different dye concentrations (1000, 1500 and 2000 mg/l) were investigated and the results compared. The results illustrate higher color removal efficiency by using the combined CW-MEC, which is a promising technique for the removal of dye in wastewater treatment.
