【摘要】：南水北调中线调水是一项复杂的系统工程,其工程设计和运行本身决定了中线原水存在安全风险,正确认识和化解这些风险对保障受水区城市供水安全意义重大。总结了中线工程设计和当前运行的若干特征,分析了总氮、氨氮、总磷和高锰酸盐指数在中线沿线的变化规律,对受水区城市接纳中线原水的水质进行了评价。在此基础上,研究认为藻类沿程生长繁殖、沼蛤大量附着生长、输水工程断水停水是中线原水的主要安全风险,并针对这些风险提出了保障受水区城市供水安全的建议措施。
[Abstract]:South-to-North Water transfer Project (South-to-North Water transfer) is a complex system project. Its engineering design and operation itself determine the existence of safety risks in the raw water of the middle route. It is of great significance to correctly understand and resolve these risks to ensure the safety of urban water supply in water-receiving areas. This paper summarizes the characteristics of the design and current operation of the middle route project, analyzes on the variation law of total nitrogen, ammonia nitrogen, total phosphorus and permanganate index along the middle line, and evaluates the water quality of the raw water of the central line accepted by the city in the receiving area. On this basis, it is considered that the main safety risks of the raw water in the middle line are algae growth and propagation along the process, a large number of clam clams attached and growth, and water cut off in the water conveyance project, and some measures to ensure the safety of urban water supply in the water-receiving area are put forward.
