摘要
人工湿地技术由于具有投资成本低、便于管理、生态化等特点,近几年在城市雨水控制利用领域得到快速发展。以马来西亚布城(Putrajaya)湿地为例,介绍了人工湿地技术在流域雨水管理中的应用。布城湿地设计过程中将水质净化、水力调节、景观美学、生态修复等多个目标统筹考虑,以确保城区人工湖水体水质满足人体接触景观娱乐用水标准,提高防洪涝标准,修复和改善生态环境,提升城市的宜居能力。湿地采用多单元和多级设计方法,以提高湿地水力性能和净化能力,最大化大型植物种植面积,同时便于湿地的维护管理。该项目近10年的运行效果表明,采用人工湿地控制雨水径流非常有效。
Constructed wetlands are becoming increasingly popular in urban stormwater management for their low investment, easy management and ecological effect. Taking Putrajaya wetland in Malaysia as example, the application of constructed wetland technology to catchment stormwater management is introduced. The multiple objectives of water quality purification, hydraulic regulation, landscape esthetics and ecological rehabilitation are taken into account as a whole in the design of Putrajaya wetland in order to ensure that the lake water quality meets the standard required for body contact recreation, increase the flood control capacity, rehabilitate and improve the ecological environment and improve urban living conditions. A multi-cell and multi-stage design is adopted to increase hydraulic performance and purification capacity, maximize areas for planting macrophytes and facilitate maintenance of the wetlands. The operation results for about ten years show that the constructed wetland is effective in stormwater runoff control.
