| Abstract |
| In this study, the use of an infiltration constructed wetland (ICW) as an eco-friendly water treatment technology for improving the quality of raw water and river water was evaluated using a full-scale test-bed built in the upper reaches of the old Seung-chon weir river channel. The average removal efficiency for the biochemical oxygen demand, suspended solids, and total phosphorus over three years was 86.8%, 96.6%, and 83.1%, respectively. However, the removal efficiency for total organic carbon and total nitrogen was relatively low, which is thought to be due to the characteristics of the influent. The general water quality constituents (BOD, SS, T-N and T-P) were not significantly different in winter when the water temperature was lower, indicating that stable water treatment over all four seasons was possible. In addition, biopolymers, humic substances, and building blocks of influent (Yeongsanriver) were able to be removed, illustrating that ICWs can be used as an effective eco-friendly water treatment technology to improve the quality of raw and river water. The removal efficiency for heavy metals, pesticides, and pharmaceuticals varied greatly, suggesting that further research is required to identify the main factors that affect there moval efficiency of ICWs. |
