| 中文摘要: |
| 大薸被广泛应用于污水处理，是一种高效脱氮除磷和吸收重金属的水生植物。本文主要采用文献调研方法，系统总结大薸对污水中污染物的净化作用，重点讨论和分析了大薸对多种污染物的去除效果、影响因素及净水机制。结果表明，大薸具有较强的营养传输能力、固碳增汇能力和多种污染物吸收能力，将其生物特性与系统环境整体及内部微生物的作用相结合，合理施用大薸对多类污水的治理均有较好的应用价值。此外，本文对大薸在除盐和抗生素方面的应用研究及建立水中养分的吸收转运模型等提出展望，旨在为大薸在污水净化中的应用提供指导。 |
| 英文摘要: |
| Pistia stratiotes L., a hydrophyte with excellent abilities in removing nitrogen or phosphorus and absorbing heavy metals, has been used widely in sewage purification treatment. To summarize the purification effect of P. stratiotes on pollutants in sewage systematically, this study mainly adopted the literature investigation method and focused on discussing the removal efficiency and analyzing the influencing factors and removal mechanism of P. stratiotes. The results showed that P. stratiotes had strong capacities of nutrient transport, carbon sequestration, and pollutant absorption. Because of the combination of the biological characteristics of P. stratiotes and the role of the system environment and microbes within it, proper usage of the plant provides good application value for the treatment of many kinds of sewage. In addition, the authors also searched for studies on salt or antibiotics removal by P. stratiotes, with the hope of establishing or improving a nutrient absorption and transport model, which could provide guidance for using P. stratiotes in sewage purification treatment. |
