水上立体人工湿地设计探讨

Innovative Design of Three-dimensional Constructed Wetland on Water

指出了随着我国水体污染和富营养化的不断加重,居民饮水安全受到了严重威胁,人工湿地系统作为净化水体的一种技术手段,起到了十分积极的作用,但因占地面积大且受气候影响大等因素限制了其发展。探讨了一种利用水上空间建立立体人工湿地的新思路,用于加强维护自然湿地,加快现有人工湿地自然化进程,降低地下水污染风险和解决湿地用地紧张的情况,以提升人工湿地系统处理污水的功能,扩大其应用范围。

With water pollution and eutrophication are getting worse and worse, our drinking water quality has been seriously threatened. As a new treatment technology, the constructed wetland plays an important role in wastewater treatment and environmental restoration. However,its application has been highly limited by large land area requirement as well as climate impacts. This article introduces a new idea in building a three--dimensional constructed wetland on water, with the aims to protect natural wetland, promote naturalization speed of current constructed wetland, and reduce contamination risk of groundwater in addition to downsize the required total land area. This design may provide significant water quality benefits while demonstrating additional benefits such as modelization and application of constructed wetland.
