北京市某水厂水源地设计取水规模为37万吨/日,一亿吨/年。共37口管井,现已全部建成并于1979.1.1投产送水。该水源地由北京市市政设计院设计,北京市第三市政工程公司施工。一、水源地位置及其水文地质条件水源地位于某河冲积洪积扇顶部向中部过渡的该河东侧河漫滩上,南北全长8公里。处于由单一的潜水向承压水过渡的潜水溢出带上,具有砂层颗粒粗、导水性能强、含水 The design water intake for a water plant in Beijing is 370,000 tons/day and 100 million tons/year. A total of 37 tube wells have now been completed and put into production in 1979.1.1. The water source is designed by the Beijing Municipal Design Institute and constructed by the Beijing Municipal Third Municipal Engineering Company. First, the location of the water source and its hydrogeological conditions The water source is located on the river floodplain on the east side of the river, which is at the top of a river alluvial and alluvial fan, and is 8 km long in the north and south. In a submerged spill zone with a single submerged transition to confined water, sand particles are coarse, water conductance is strong, and water contains
