【摘要】 人工填料强化生态浮床是近年来发展起来的一种新兴生态工程修复技术。选取3种不同类型的人工填料与挺水植物组合,分析其对高磷浓度养殖水体和上海市养殖池塘水体的净化效果。结果表明,在高磷浓度（2.36～3.42 mg/L）养殖水体中,人工填料强化生态浮床对TN、TP、COD的平均去除率分别为34.9%,12.2%,26.1%,且3组系统之间差异不明显。在上海市养殖水体平均浓度条件下,3组系统对TN和TP的去除能力为:立体弹性填料强化生态浮床>组合填料强化生态浮床>生物绳填料强化生态浮床,立体弹性填料强化生态浮床对TN和TP的去除率分别为83.9%和69.3%;3组系统对COD和NH₄⁺-N的去除率均在70%以上。因此,立体弹性填料强化生态浮床可以考虑应用于上海市淡水养殖池塘水体的生态修复工程。更多还原

【Abstract】 Enhanced floating treatment wetland（EFTW） with biofilm carriers is a new ecological restoration technology developed in recent years. In this study, three kinds of biofilm carriers were added into traditional floating treatment wetland（FTW）. Their purifying effects on high phosphorus-concentration aquaculture water and aquaculture pond water in Shanghai were examined. Results elucidated that in high phosphorus-concentration（2.36-3.42 mg/L） aquaculture water, the average removal rates of TN, TP and COD were 34.9%, 12.2% and 26.1%, respectively, with no significant difference among the three treatment groups; in aquaculture pond water in Shanghai with average polluted level, EFTW with elastic packing had the best ability of purifying TN and TP with the removal rate reaching 83.9% and 69.3%, respectively, followed by EFTW with combined packing and EFTW with bio-cord packing. The removal rates of COD and NH₄⁺-N by the three treatment systems all exceeded 70%. In conclusion, EFTW with elastic packing can be applied to the ecological restoration project in freshwater aquaculture ponds in Shanghai.更多还原
