我国最大规模人工湿地公园开工
 
云南省九溪人工湿地公园(二期扩建工程)近日开工,湿地日处理量共约20万吨,总占地面积约1112亩,为国内处理自然水体水质为主要功能的最大规模人工湿地。九溪人工湿地(二期)扩建工程主要承接上游污染的星云湖水和九溪大河河水。根据工程设计方瓦地(WADI)设计和华北市政院团队提供的数据显示,湿地日常出水能够满足地表水III类的标准并供给下游城市使用,极大的修复了区域生态,洪水期间能够提供10万立方米的洪水蓄洪利用空间。
 
人工湿地二期的组成分为4套工序系统,分别是预处理系统、前处理系统、主处理系统和后(末端)处理系统,主要工艺采用多级潜流强化净化工艺(MESF)。二期工程共将秉承人工湿地+公园“一体化设计”的理念,希望成为一个集生态、水处理、休闲、科普的田园综合体。欧美国家投入建设和运行的人工湿地已经近十万座,在解决流域水质问题方面,和传统污水厂发挥同样重要的作用。在中国,作为绿色基础设施的典型代表,人工湿地具备将解决城市水污染问题和生态空间建设结合起来的潜力,“人工湿地+公园”的新模式已经呼之欲出,九溪人工湿地公园即为此方面的典型中国代表项目。
 
 
Construction Breaks Ground on Jiuxi Constructed Wetland Park

Jiuxi Constructed Wetland Park (Phase II Extension Work) in Yunnan Province has been under construction and officially celebrated recently. Within this green-blue plan from WADI team aiming for improving water system, the ca. 74 ha. Former agriculture land is to be transformed into a natural park which cleanses 200,000 tons of pollutant upstream water(Xingyun Lake and Jiuxi River catchment)daily, presenting the largest constructed wetland project in China. The wetland effluent should meet the Class III surface water quality standard, while repairing ecological structure in the region. In addition, it is capable to provide 100,000 cubic meters of retention space during extreme flooding event.
 
Phase II consists of four treatment units: pretreatment unit, the second pretreatment unit, main treatment units and terminal treatment unit. The main treatment unit adopts multiphase submerged flow purification (MESF) process. Phase II upholds an "integrated approach" synergizing eco-engineering, water treatment, leisure function and public participation. It creates an ecological poetry that settles into its genius loci and people, while simultaneously functioning itself as a super water machine.
 
Nearly more than 100,000 constructed wetlands have been in operation in European and American countries. They play a crucial role in managing water quality. With a new emerging paradigm of "Constructed Wetland + Park", Jiuxi wetland park is a Chinese showcase demonstrating how water engineering can harmoniously interweave nature and culture, water process and ecology repairing. It is expected to be completed in the end of 2019.
