摘　　要：二十埠河作为南淝河主要支流,其水质直接影响着南淝河及巢湖水生态安全。本研究拟通过旁路净化湿地净化二十埠河水质。在挖方量、填方量、水位影响范围、影响截流设施个数、工程投资及运行费用等方面,分别对旁路湿地自流进水自流出水、泵提进水自流出水(建坝、不建坝)和自流进水泵提出水4种进出水方式进行论证分析。结果表明,相较于泵提进水自流出水(建坝、不建坝)和自流进水泵提出水,自流进水自流出水方式具有年运行费用低、湿地运行维护方便、场地内部土方可实现土方平衡等优点,更适用于南淝河旁路人工湿地工程。As a major tributary of the Nanfei River,the water quality of the Twenty Bu River directly affects the ecological security of the Nanfei River and Chaohu Lake.This study aims to purify the water quality of the Twenty Bu River through bypass purification wetlands.In terms of excavation volume,filling volume,influence range of water level,number of closure facilities affected,project investment and operation cost,four water inlet and outlet modes were discussed and analyzed respectively.The water inlet and outlet modes were gravity inflow and gravity outflow,pump inflow and gravity outflow with dam construction,pump inflow and gravity outflow without dam construction,and gravity inflow and pump outflow.The results showed that compared with the other three methods,the gravity inflow and gravity outflow method had the advantages of low annual operation cost,convenient wetland operation and maintenance,and earthwork balance within the site.It was more suitable for Nanfei River bypass constructed wetland project.
