摘要
通过给水管网的水质模型推导得出了节点水龄的计算公式 ,给出了以节点水龄量度的给水管网水质状况曲线 ,并以此为基础 ,针对某大城市给水管网进行了节点水龄实例计算 ,绘制出整个给水管网等水龄线及节点 2 4h水龄变化曲线图 ,从而得出该城市给水管网基于节点水龄的水质状况。管网节点水龄的计算对从理论上分析给水管网的水质以及对提高给水系统的服务水平均具有重要意义。
The formula to calculate the node water age in a water distribution network has been deduced from the network water quality model, and water quality curve has been given by plotting the values of water quality index vs the node age. As a real example, the node age of the distribution network of a big city has been calculated on the basis of the above theory. Then the contour of node age for the whole distribution network and the varying curve of node age for a certain node during 24 hours are drawn. From these, for the distribution network of this city, water quality status based on node age has been obtained.certainnodeduring 2 4hour
