摘要: 通过模拟不同程度富营养化水体,研究凤眼莲、水芙蓉和莲花竹在不同处理浓度水体中对氮、磷的去除效果。结果表明:凤眼莲、水芙蓉和莲花竹对水体中的氮、磷都有一定的去除效果,经过30 d的净化试验,凤眼莲对氮、磷去除率分别为50%~78.46%和68.16%~89.56%,水芙蓉对氮、磷去除率分别为57.58%~76.87%和72.28%~76.47%,莲花竹对氮、磷去除率分别为0.60%~10.80%和2.48%~10.04%。在现场试验中,水体中总氮和总磷分别降低了31.17%和20.48%,由此可见,凤眼莲和水芙蓉对氮、磷有较好的去除效果,能够改善富营养化水体。

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
