水力模型在城市污水管网系统改造中的应用

利用InfoWorks ICM软件建立污水系统水力模型,对污水管网运行状况进行仿真模拟,在模型计算值与实测数据对比满足校核精度要求的前提下,利用水力模型对改造方案进行验证,保证方案的可行性和合理性。以广州市大坦沙污水系统-石井污水系统调水工程为研究对象,应用水力模型对改造方案实施前后的主干管运行超载状况、污水溢流状况和污水厂运行负荷进行评估分析,为该区域污水系统改造方案的可行性分析提供理论依据。

Application of hydraulic model in urban sewage network transformation

InfoWorks ICM can be used to build sewage system hydraulic model and realize the simulation of sewer pipe network's operating condition.If the calculated values and the measured data meet the checking accuracy requirement,transformation programs can be validated by the hydraulic model to assess the feasibility.The paper takes the diversion project of Datansha sewage system-Shijing sewerage system in Guangzhou as the research object.By using the computer simulation technology,the hydraulic model is built to assess and analyze the condition of trunk pipeline running overload,sewage overflow and plant operation load,which may provide theoretical basis for feasibility analysis of transformation program.
