摘要: 在对南方地区水生植物全面了解的基础上,选择凤眼莲、长鬃蓼、美人蕉、短叶茳芏、鸭趾草、空心莲子草和风车草7种南方地区最常见的水生植物作为研究对象,分别从7种水生植物对城市生活污水中NH3-N、TN和TP等污染的净化效果进行研究,结果表明,7种植物对生活污水中的NH3-N、TN和TP等污染成分都有一定的去除效果,其中凤眼莲对NH3-N去除能力最好,美人蕉对TN、TP去除能力最好。Abstract: Based on the comprehensive understanding of hydrophytes in southern regions of China, this research used seven hydrophytes most common in the south regions as research objects to compare their treatment effects on NH3-N, TN and TP in domestic sewage. Results showed that all the seven hydrophytes had treatment effects on NH3-N, TN and TP to some extent. The hydrophyte species possessing the highest absorption capacity for NH3-N is Eichhornia crassipes, and the species possessing the highest absorption capacities for TN and TP is Canna indica.
