【摘要】 密云水库是北京市重要的地表饮用水源地，面源污染是水库入库污染的主要来源。文章从源头控制、过程阻断、末端控制三方面展开密云水库面源污染防治技术研究，提出水库面源污染控制最佳管理措施(BMPs)技术体系。源头控制：推广梯田建设或鱼鳞坑整地的保护性耕作措施，加强畜禽养殖污染防控和化肥、农药的合理施用；过程阻断：布施植物篱，在水库上游划定河岸缓冲带/植被过滤带等；末端控制：修建前置库、人工湿地，耦合曝气氧化沟、稳定塘等技术，提高污染物去除效能。该技术体系的构建可为密云水库面源污染防治提供理论及技术支撑。更多还原

【Abstract】 Miyun Reservoir is an important surface drinking water source in Beijing, and non-point source pollution is the main source of reservoir inflow pollution. This paper studies the prevention and control technology of non-point source pollution in Miyun Reservoir from three aspects: source control, process blocking and terminal control. On this basis, a technical system of best management measures(BMPs) for reservoir non-point source pollution control was proposed. Best management measures based on source control are promoting protective tillage measures such as terrace construction or fish scale pit preparation, strengthening pollution prevention and control of livestock and poultry breeding, and rational application of chemical fertilizers and pesticides. Process blocking are plant hedgerows, and delineate riparian buffer zones or vegetation filter belt in the upper reaches of reservoirs, etc. Terminal control measures include build pre-storage, artificial wetland, coupled aeration oxidation ditch, stabilization pond and other technologies to improve pollutant removal efficiency. The construction of this technical system can provide theoretical and technical support for the prevention and control of non-point source pollution in Miyun Reservoir.更多还原
