选用美人蕉作为浮床植物,引入固相碳源作为基质,组建竹丝基质生态浮床( FI-BT)和稻草基质生态浮床( FI-RS)两组平行系统,比较了两种生态浮床净化富营养化水体的效果及特性。实验结果表明:FI-BT在去除水体中的NH4+-N和TP方面的效果较佳,试验开始后第6天的平均去除率分别为92.13%±0.06%和34.09%±0.2%;FI-RS在第6天的平均去除率分别为91.6%±0.06%和24.05%±0.18%。 FI-BT相比于FI-RS在反硝化上更有优势。

Two sets of parallel systems of floating islands with bamboo thread ( FI-BT) and rice straw( FI-RS) respectively are developed by selecting canna plants as the floating island plant and introducing the solid carbon source as the matrix, and the efficiency and characteristics of their eutrophic water purification are compared. The experiment results show that FI-BT is bet-ter for removing NH4+ -N and TP from the water;the average removal rate of FI-BT is 92. 13% ± 0. 06% (NH4+ -N) and 34. 09 ± 0. 2% (TP) respectively on the sixth day while that of FI-RS are 91. 6 ± 0. 06% and 24. 05 ± 0. 18%. So, FI-BT is su-perior in denitrification compared with FI-RS.
