In this study, a new type of ecological floating bed (NT-EFB) employing ornamental plants (either Spathiphyllum floribundum, Hydrocotyle sibthorpioids, Chlorophytum comosum or Peperomia obtusifolia) was designed to purify confected eutrophic water for 39 days. The growth characteristics of the plants and the effect of water treatment were analyzed and compared. The results showed that: (1) all the four ornamental plants examined survived well in the eutrophic water and an increase of plant biomass was observed; (2) the degradation efficiency of TOC by adding plants was about 85.0%; (3) the removal rate of NH₄⁺–N was about 97.0%; (4) all the four plants can be used as floating bed plants to treat eutrophic water and Hydrocotyle sibthorpioids had the best growth characteristics and treatment efficiency. The study provides an adequate reference for the treatment of eutrophication using ecological floating beds.

在这项研究中，设计了一种新型的生态浮床（NT-EFB），采用观赏植物（Spathiphyllum floribundum，Hydrocotyle sibthorpioids，Chlorophytum comosum或Peperomia obtusifolia）净化对流的富营养化水39天。分析并比较了植物的生长特性和水处理效果。结果表明：（1）所研究的四种观赏植物均在富营养化的水中存活良好，并观察到植物生物量的增加。（2）添加植物对TOC的降解效率约为85.0％；（3）NH ₄ ⁺的去除率-N约为97.0％；（4）这四种植物都可以作为浮床植物来处理富营养化水，而水生的油生植物的拟南芥具有最佳的生长特性和处理效率。该研究为利用生态浮床处理富营养化提供了充分的参考。
