摘　　要：为研究河道内源污染治理方式,对河道防洪标准和水质产出目标进行分析,确定污染河道清淤范围和施工方法。分析了潮水水位和河道行洪能力,圈定了清淤范围和纵向清淤深度。分析内源污染污染物负荷和底泥物化性质,确定河道清淤厚度及泥浆处理要求。为实现河道环保清淤施工,采用水力冲挖排干清淤施工方法,实现目标污染物的有效去除,降低了河道清淤方量。通过控制多级泵送系统传输压力,实现了长距离、高陡坡泥浆传输。To study the internal pollution control methods of river channels,analyze the flood control standards and water quality output targets of river channels,determine the scope of dredging and construction methods for polluted river channels.Analyzed the tidal water level and flood discharge capacity of the river channel,delineated the dredging range and longitudinal dredging depth.Analyze the load of endogenous pollutants and the physicochemical properties of sediment,and determine the thickness of river dredging and mud treatment requirements.In order to achieve environmental protection and dredging construction in river channels,the hydraulic flushing and dredging construction method is adopted to effectively remove target pollutants and reduce the amount of river dredging.By controlling the transmission pressure of the multi-stage pumping system,long-distance and steep slope mud transmission is achieved.
