人工湿地植物的选择及植物净化污水作用研究进展

Research Progress of Selection of Plants for Constructed Wetlands and Effect of Plants' Purification on Sewage

人工湿地系统具有强大的净化污水功能。植物是人工湿地系统中的核心部分,在净化污水过程中起着至关重要的作用。介绍了为人工湿地选择植物时需要考虑的因素和基本原则;总结、评述了植物在人工湿地净化污水中的作用及其影响因素方面的研究;针对目前相关研究中存在的问题,展望了未来研究的方向。

Constructed wetland system has unique and powerful purification functions. Plants, as the essential components, play a significant role in the purification process. This paper addresses the basic principles and the factors needing to be considered while selecting plants for constructed wetland system, reviews the worldwide studies on wastewater purification with the plants in the constructed wetlands in the recent decades and summarizes their functions and influencing factors in purification of the constructed wetlands. Finally, some suggestions for future studies are also proposed according to the existing concerns in the current studies on plants in the constructed wetlands.
