摘要
污水管网模拟的关键在于准确估算污水流入量,而现有的估算方法依赖统计资料且精度较低.提出了一种基于信息点(POI)的污水量估算方法,利用开源POI数据分析了不同建筑类型的用水量,通过欧式距离关联计算检查井流量,构建了污水管网模型并结合监测数据和ES算法进行校核.应用于某小型城市污水管网,以流量监测数据校核,液位监测数据验证.结果表明除个别节点外,该方法明显优于传统的管长流量估算方法,NSE和KGE系数均在0.9以上,可以精准高效地对污水管网进行动态模拟.
Abstract
The key to simulating a sewage network is to accurately estimate the amount of sew-age inflow,while existing estimation methods rely on statistical data and have low accuracy.This paper proposes a sewage volume estimation method based on information points(POI).The water consumption of different building types is analyzed using open-source POI data,and the flow of in-spection wells is calculated by Euclidean distance association.A sewage network model is construc-ted and calibrated with monitoring data and ES algorithm.It is applied to a small urban sewage network,calibrated with flow monitoring data and verified with liquid level monitoring data.The results show that,except for individual nodes,this method is significantly better than the tradi-tional pipe length flow estimation method,with NSE and KGE coefficients both above 0.9,and can accurately and efficiently simulate the sewage network dynamically.
