秦淮区北部水系引补水方案模拟

为获取南京市秦淮区北部片区新建净水站的建设规模和补水线路,采用MIKE11的HD、AD模块耦合建立秦淮区北部片区河网一维水质模型,以氨氮和悬浮物作为研究对象,对不同补水规模和补水线路下的片区水质变化情况进行模拟。结果表明,从水质改善效果和经济角度分析,18万t/d建设规模和出水管接至外秦淮河副支的方案组合较为适宜。

Simulation study on water diversion scheme in northern river network of Qinhuai District

In order to analyze the scale and water supplement route of a new water purification station in the northern area of Nanjing Qinhuai District, a one-dimensional water quality model of river network was established by coupling HD and AD modules in MIKE11. Ammonia nitrogen and suspended solids were selected as the research objects and the variation of water quality under different water supplement scales and water supplement routes was simulated. The result shows that the scale of 180 000 t/d for the new water purification station and connection of the outlet pipe to the sub branch of the Qinhuai River is appropriate.
