Evaluation of Organic Matter Removal Efficiency and Microbial Enzyme Activity in Vertical-Flow Constructed Wetland Systems

Abstract: Abstract:In this study, enzyme activities and their relationships to organics purification were investigated in three different vertical flow constructed wetlands, namely system A (planting Pennisetum sinese Roxb), system B (planting Pennisetum purpureum Schum.), and system C (no plant). These three wetland systems were fed with simulation domestic sewage at an influent flow rate of 20 cm/day. The results showed that the final removal efficiency of Chemical Oxygen Demand (COD) in these three systems was 87%, 8… Show more

“…Therefore, cost-effective and environmentally sound methods of treating wastewaters are needed. Constructed wetlands have gained popularity from the last several years and have been used as an alternative to conventional wastewater treatment methods [3] because of their easy maintenance and operation, low energy consumption, and water recyclability [4,5]. Constructed wetlands are successfully used to treat different types of wastewater [6][7][8][9][10][11][12][13].…”
