【摘要】 介绍了北京奥林匹克森林公园人工湿地系统的设计,跟踪调查了复合垂直流人工湿地在龙型水系水质改善中的功能和效果。复合垂直流人工湿地系统占地面积为41 500 m2,处理水量为2 600 m3/d的污水处理厂尾水(再生水)和20 000 m3/d的主湖循环水。一年多的运行表明,该系统与其他生态工程的协同作用有效地改善了公园内的龙型水系水质,特别是在奥运期间,在保证了奥运主湖水质良好的同时,为运动员和观众提供了优美的休息环境,取得了良好的生态、环境、经济和文化等综合效益。更多还原

【Abstract】 The design and operation effect of the constructed wetland system in Beijing Olympic Forest Park(BOFP) are introduced.The integrated vertical flow constructed wetland(IVCW) has a surface area of 41 500 m2 and a design capacity of 2 600 m3/d tailwater from the WWTP and 20 000 m3/d circulated water of the main lake.The operation for more than one year shows that the synergism of the system with other ecological engineering improves the water quality of dragon-shaped water system in the park.During the period of Beijing 2008 Olympic Games,it improves the ecological environment of the park and beautifies the park landscape while ensuring the good quality of the main lake.更多还原
