Abstract: We studied the effects of floating macrophytes on eutrophication water under different nutrition conditions. Eichhornia crassipes, Pistia stratiotes and Dracaena sanderiana can eliminate total nitrogen(TN) and total phosphorus(TP) in water. After growing 30 days, TN and TP removal rates were 50%-78.46% and 68.16%-89.56% by E.crassipes, respectively. TN and TP removal rate were 57.58%-76.87% and 72.28%-76.47% by P.stratiotes, respectively. TN and TP removal rate were 0.60%-10.80% and 2.48%-10.04% by D.sanderiana, respectively. TN and TP removal rate were 31.17% and 20.48% by E.crassipes and P.stratiotes from treated water in the outdoor experiment. Thus, E.crassipes and P.stratiotes have good removal effect on nitrogen and phosphorus of eutrophication water.

Key words: floating macrophytes, eutrophication, total nitrogen, total phosphorus
