Abstract

Wetland systems are widely accepted natural water purification systems around the world in nonpoint sources pollution control. In this study, the field experiment to reduce nonpoint source pollution loadings from agricultural drainage and polluted stream waters using wetland and pond system was performed. The removal rate of $BOD_5$, TSS, TN, TP, and $Chl-{\alpha}$ was 52%, 90%, 56%, 59%, and 81%, respectively. Performance of the experimental system was compared with existing data base (NADB), and it was within the range of general system performance. Overall the water quality improvement was apparent in wetland and pond system.
