  • This study was aimed at the improvement of the effluent quality of municipal wastewater treatment plant by Oenanthe javanica and Bio-string media. The results were compared with conventional sedimentation tank and pilot sedimentation plant. In this study BOD as organic pollutants, SS, Nitrogen and Phosphorus were tested to evaluate the removal efficiencies for the advanced treatment. The result were as follow: in the Pilot Plant experiment, Tank 2 was fairly high removal efficiency as compared with Tank 1. The removal efficiency of BOD and SS in Tank 2 were as a range of $7.9%{\sim}38.8%,\;14.3%{\sim}60.0%$ and the removal efficiency of T-N, T-P were a range of $9.6%{\sim}31.5%,\;33.0%{\sim}80.0%$ respectively. The removal efficiency of T-P and SS were much higher than BOB and T-N.
