| 摘 要： | 利用美人蕉和菖蒲生态浮床净化微污染源水,在进水TN为0.91～1.17mg/L、TP为0.12～0.18mg/L、CODMn为5.48～9.36mg/L、DO为3.6～6.1mg/L时,两种生态浮床的出水水质均能满足集中式饮用水水源地水质标准(GB3838—2002)的要求;其中美人蕉和菖蒲浮床对TN的平均去除率分别为42.5%和36.2%,对TP的平均去除率为48.1%和44.2%,对CODMn的平均去除率为42.3%和36.3%,美人蕉浮床的净化效果要好于菖蒲浮床。可见,生态浮床的除污效果较好,可用于微污染源水的净化。

| Abstract: | Canna indica and Acorus calamus ecological floating beds were used to purify micro-pol-luted source water. When the influent TN, TP, COD_(Mn) and DO are 0.91 to 1.17 mg/L, 0.12 to 0.18 mg/L, 5.48 to 9.36 mg/L and 3.6 to 6.1 mg/L, respectively, the effluent purified by the two floating beds can satisfy GB 3838 -2002. The ecological floating beds planted with Canna indica and Acorus cal-amus exhibit average removal efficiencies of 42.5% and 36.2% for TN, 48.1% and 44.2% for TP, 42.3% and 36.3% for COD_(Mn), respectively. Canna indica has better treatment performance than Acorus calamus. The ecological floating bed has a significant purification effect, and therefore can be applied to treat micro-polluted source water. |
