外文摘要：The effects of species compositions (two-species mixtures or monocultures) and hydraulic retention times (HRT; 1, 4, 8, 16, 24, 48 hours) on total nitrogen (TN) and total phosphorus (TP) removal from eutrophic water were studied in a constructed wetland. Two species mixtures showed higher efficiency to remove TN and TP than monocultures. Average removal efficiency of TN and TP was 49.6% and 34.0%, respectively. A longer HRT enhanced the removal efficiency of TN and TP, which suggested that species mixtures, HRT, and species mixtures x HRT interaction were useful for increasing the wastewater TN and TP removal.
