Abstract:: In order to find a feasible phytoremediation to restore severe eutrophic water, two aquatic macrophytes Elodea nuttallii and Jussiaea stipulacea Ohwi were employed in floating artificial eutrophic water to get insight into differences involved in nutrient removal during incubation periods. The results illuminated that the removal percentages of total nitrogen(TN), ammonium(NH₄-N), nitrate, phosphorus(TP), COD and Chlorophyll by Elodea nuttallii were 62.9%, 90.83%, 53.90%, 71.21%, 43.33% and 50.05%, respectively, Corresponding pecentages for Jussiaea stipulacea Ohwi were 93.56%, 97.38%, 99.44%, 97.74%, 52.49% and 58.34%, respectively. Analysis of variance revealed difference of removel effects between two aquatic macrophytes was significant(P<0.05). So Jussiaea stipulacea Ohwi is suited to restore severe eutrophic water because of its strong nutrient removal ability, while Elodea nuttallii can play great role in maintaining the water quality.
