摘要
某市自来水公司完成某路段球墨铸铁管管网施工通水后,该管网下游部分区域自来水烧开后呈现长时间白色浑浊现象,为此结合该时段施工情况对水泥砂浆内衬管(特别是离心方式涂覆内衬的管道)通水初期对供水水质的影响进行了研究,并应用水力模型对污染物扩散规律进行模拟,提出了保障水质安全的相应措施,可为新建管道的运行维护提供参考。
After the completion of construction and running of a section of ductile iron pipe network, white turbidity phenomenon occurred in boiled drinking water in the downstream area of the network for a long time. Therefore, the initial effect of the cement mortar lining especially centrifugally coated lining on water quality was investigated. The diffusion rule of pollutants was simulated by using hydraulic model, and appropriate measures to ensure water quality safety were proposed, which can provide a reference for the running and maintenance of new pipeline.
