城郭河白腊湾段近自然河道湿地设计及冬季运行效果
|
摘要
针对南水北调东线南四湖流域之城郭河水体生态净化及河流生态廊道建设的需求,在城郭河白腊湾段设计并建设了近自然河道湿地水质净化工程。根据因地制宜的原则,工程整体采用了生态护岸+湿地植物配置+生物飘带的河道原位生态修复组合工艺方案。根据冬季水质监测分析结果,城郭河白腊湾河道湿地冬季出水COD、NH_3-N和TP等主要水质指标均达到了GB 3838—2002《地表水环境质量标准》Ⅲ类标准,在支撑南四湖入湖河流城郭河与南水北调东线调水水质安全的同时,恢复了河道走廊的生态功能。
According to the requirements of water ecological purification and river ecological corridor construction for Chengguo River, which belongs to the Nansihu Basin along the eastern route of South-to-North Water Diversion Project, a water purification engineering of near natural river wetland was designed and constructed at the Bailawan Section of the river. A combined design of in-situ river ecological restoration composed by ecological revetment+wetland plant configuration+biological ribbon was utilized based on local conditions. With the results of water quality monitoring and analysis at 7 cross-sections, COD, NH_3-N and TP for the Bailawan river wetland at Chengguo River were demonstrated approaching the class Ⅲ of Environmental Quality Standard for Surface Water. The construction of the wetland can restore the river ecological function, while supporting the water quality safety.
