摘　　要：管道冲洗是保证供水安全的重要手段,北京市现状供水管网冲洗时根据现状管线的具体情况,多采用传统单向水冲洗、气水冲洗等管道冲洗技术,确保供水管网水质安全。传统单向水冲洗、气水冲洗技术冲洗管网后,其冲洗效果维持时间短。文中以北京市首次应用冰浆冲洗技术冲洗某市政供水管道为例,详细介绍了被冲洗管道的基本情况,并对管道冰浆冲洗作业流程进行了归纳和总结。通过收集整理和分析管道冰浆冲洗过程中的水质监测数据,对冰浆冲洗效果进行了分析与探讨。冰浆冲洗结果表明,冲洗后管道内壁附着的大量污染物被冲洗排出,管网水浑浊度降低了80.86%,管道内水质达到《生活饮用水卫生标准》(GB 5749—2022)的要求。研究可为其他省市自来水公司管道冲洗提供借鉴和参考。Pipeline flushing is an important means to ensure water supply safety.When flushing the current water supply network in Beijing,traditional one-way water flushing,gas water flushing and other pipeline flushing techniques are often used based on the specific situation of the current pipeline to flush the current pipeline and ensure the water quality safety of the water supply network.This article takes the first application of ice slurry flushing technology in Beijing to flush a municipal water supply pipeline as an example,and provides a detailed introduction to the basic situation of the flushed pipeline.The operation process of pipeline ice slurry flushing is summarized.By collecting,organizing and analyzing water quality monitoring data during pipeline ice slurry flushing,the effect of ice slurry flushing is analyzed and discussed.The results of ice slurry flushing show that a large amount of pollutants attached to the inner wall of the pipeline are flushed out after flushing,and the turbidity of the water in the pipeline network is reduced by 80.86%.The water quality in the pipeline meet the requirements of the Standards for Drinking Water Quality(GB 5749—2022).The study can provide reference and guidance for pipeline flushing in other provinces and cities.
