提高生态浮岛对受污染水体净化效率的研究进展

Research Advances in Improvement of Purification Efficiency of Ecological Floating Island for Polluted Water Body

生态浮岛适用于治理景观水体及河湖受污水体,但传统生态浮岛的净化效率受多种因素制约。在详述生态浮岛组成结构基础上,综述了提高其净水效果的强化措施,并指出目前理论研究和实际应用间存在的差异以及各自的缺点和发展前景。生态浮岛结合物理、化学和生物法、优化浮岛组成、结构及布置均起到强化净水效果的作用。提高生态浮岛净水效果的理论研究丰富,但实际工程运行效果与理论研究成果差距明显。未来研究应着重于提高实际工程运行效果、探索生态浮岛其他应用功能(提供能源、缓解用地紧张)。

Ecological floating island(EFI) is suitable for the treatment of polluted landscape water, river and lake body, but the purification efficiency of traditional EFI is restricted by many factors. Based on the detailed description of its composition and structure, this paper systematically summarizes the enhanced measures of the improvement of the purification efficiency. And it points out the differences between current research and practical applications, also their own shortcomings and development prospects are showed. Combining physical, chemical and biological methods with EFI, optimizing the components, structure and arrangement of EFI both play a role in the enhancement of the purification efficiency. There is a significant gap between the operation effect of actual project and the theoretical research results of EFI, though the theoretical research on the improvement of the water purification effect of EFI is plentiful. The future research should focus on improving the operation effect of actual project and exploring other application functions of EFI(providing energy and alleviating land tension).
