摘　　要：详细探讨了给水管网中金属管、石棉水泥管、水泥管、塑料管 ,以及管道内壁沥青涂层、水泥沙浆衬里等对供水水质的影响 ;这些影响因素包括管材的腐蚀、细菌的再生长、化学物质的渗入 ,等等 .结合实验室及现场测试研究了供水水质在管道输送过程中所发生的变化等问题 ,指出采用经过严格毒物学及微生物学测试的管网材料才是解决管网水质污染的有效途径 .The paper discusses in detail the effects of metal pipe, asbestos-cement pipe, cement pipe, plastic pipe as well as asphaltic coat and cement-mortar linings in water supply pipelines on the quality of water supply including corrosion of pipe material, bacterial after-growth and seepage of chemical material, reviews the changes in quality of water in water supply pipelines through laboratory and field resting, and points out that toxicological and microbiological testing is an efficient way to ensure quality of water in pipelines.
