摘要:
选取5种典型水生植物菖蒲、千屈菜、旱伞草、水葫芦、黑藻，研究各单种植物单元对模拟富营养化水体生态系统的净化效果。结果表明：5种水生植物均能在富营养化水体中正常生长，对水体中的氮、磷均有一定的净化效果。5种植物去氮能力的大小依次为水葫芦>黑藻>旱伞草>菖蒲>千屈菜，5种植物去磷能力的大小依次为水葫芦>旱伞草>黑藻>菖蒲>千屈菜；5种植物对氮的累积率为10.49%—60.73%，对磷的累积率为13.45%—43.55%；5种植物对氮、磷的去除贡献率分别为61.65%—75.93%，45.66%—68.81%。试验证明，5种植物均可有效应用于城市富营养化水体中氮、磷的净化。
Abstract:
Five typical aquatic plants, Acorus calamus, Lythrum salicaria, Cyperus involucratus, Eichhornia crassipes and Hydrilla verticillata, were selected to study their purification effect on the simulated eutrophic water ecosystem. The results showed that all the five aquatic plants could grow normally in eutrophic water and had certain purification effect on nitrogen and phosphorus in water. Their nitrogen removal ability was shown in order, as E. crassipes, H. verticillata, C. involucratus, A. calamus and L. salicaria, and their phosphorus removal ability shown in order, as E. crassipes, C. involucratus, H. verticillata, A. calamus and L. salicaria. Their cumulative rates of nitrogen and phosphorus were 10.49%—60.73% and 19.3%—43.55%, respectively. Their contribution rates of nitrogen and phosphorus removal by these five plants were 61.65%—75.93% and 45.66%—68.81% respectively. It was concluded that these five plants could be effectively applied to the purification of nitrogen and phosphorus in urban eutrophic water.
