A comparative study of vertical flow and free-water surface constructed wetlands for domestic wastewater treatment and its greenhouse gases emission
1. IntroductionConstructed wetland (CW) systems are reliable, flexible in design, and can be built, operated, and maintained at lower costs compared to conventional methods of chemical treatment. Therefore CW systems are widely used for controlling water-body eutrophication as an easy-operation and cost-effective ecological technology in developing countries. However, growing attention has been paid to its greenhouse side-effect and global-warming potential in recent years. Two typical constructed wetlands: Vertical flow (VF) and Free-water Surface (FWS) constructed wetlands were used in this study. The aims of this research are not only to compare the nutrients removal performance for treatment of low C/N ratio loading domestic wastewater, but also to investigate and compare their CH4 and N_2O greenhouse gas emissions characteristics.
