In this study, we investigated the performance of phytoremediation system treating wastewater containing high level of nutrients. Use of Acorus gramineus showed high removal efficiency for nitrogen (N) and chemical oxygen demand (COD) but low removal efficiency for phosphorus (P). The Overall N, P and COD removals efficiencies were 83.0-90.8.%, 12.8-40.6% and 72.6%, respectively. During the 9day operation of the system, The pH of effluent has significantly decreased comparing with raw water The mean pH of influent and effluent water was 6.0 and 7.0, respectively.
