城市排水系统水质模型的构建及应用

Development and Application of Water Quality Model for Urban Drainage System

采用Info Works ICM商业软件构建了城市密集建成区某流域排水系统的水质水量模型,同时,对研究流域的市政排水管线的关键节点实施水量水质同步连续监测,将实测数据运用于模型校核率定,建立了较为精确的流域排水系统水质模型;最后利用建立的水质模型对流域主要污染物的排放量进行了核算,发现除SS外,其余均与相关规范的标准值偏差不大。阐述的方法及流程具有通用性,可以为其他流域排水系统水质水量模型的构建提供参考。

The InfoWorks ICM software was adopted to build the water quality and quantity modelfor a drainage system in the city＇ s densely buih-up area. The water quantity and quality at the key nodes of the drainage system were continuously and synchronously monitored, and the measured data were applied to the model calibration to ensure its accuracy. The model was adopted to calculate the emissions of major pollutants. The deviation of the calculated values from the standard values was small, except SS. The method and process set forth herein are universal, so they can provide a reference for building the water quality and quantity models for drainage systems in other regions.
