Abstract

Constructed wetlands have become a popular technology for treating contaminated surface and wastewater. In this study, the field experiment to reduce nonpoint source pollution from watershed runoff during rainy day using wetland and pond. TSS and T-N removal rate of wetland-pond system and pond-wetland system was 91% and 73%, 94% and 70%, respectively and values were same range. $BOD_5$ and T-P removal rate of pond-wetland system (38% and 78%) was higher than wetland-pond system (27% and 62%). overall, pond-wetland system is more useful than wetland-pond system to control NPS.
