生活饮用水管网中水质影响因素的研究探讨
【摘 要】生活饮用水的水质健康安全对人们身体健康有着非常重要的作用。随着人们生活节奏的加快以及生活质量的提高，对饮用水的质量要求也开始越加重视，但是目前生活饮用水的安全却让人们越来越担心，对水质健康要求也愈加重视，但是目前影响水质健康的因素有很多，主要包括水质来源、运输网管以及处理设施程序等。本文主要研究我市自来水厂生活饮用水公司运输网管，对饮用水出水水质以及网管末梢水质进行主观状指标、一般化学指标以及细菌学的对比研究分析，发现用户所用的饮用水水质来源以及输水管网材质和使用年限、二次供水设施情况的影响，并从运输管道材质的选择、消毒副产物的控制和对管道的技改、清洗等方面提出了改进建议。

Water quality impact study of the factors in the drinking water pipe network
【Abstract】Health and safety of the water quality of drinking water has a very important role in the health of people. With the quickening pace of people’s lives, as well as improved quality of life, the quality requirements of drinking water also began to increasingly great importance, but the safety of drinking water allows people increasingly worried about health requirements also pay more attention to water quality, but there are many factors that affect water quality health, including water sources, transportation network and treatment facilities procedures. This paper studies the transport network of the city water plant for drinking water companies, water quality of drinking water and the water quality of the network peripheral subjective shaped indicators, the comparative study of the general chemical indicator and bacteriological analysis, found that the drinking water used by the user material and the useful life of water sources and water distribution network, the impact of the secondary water supply facilities, and selection of materials from the pipelines, the control of disinfection byproducts, and technological transformation, cleaning and other aspects of the pipeline is put forward suggestions for improvement.

近年来，随着城市居民的生活水平的不要提高，经济的快速发展带来的是人们对生活饮用水的水质要求增高，一开始被广大市民所重视。目前，城市重工业发展较快，同时带来的环境水污染较重，同时居民饮用水污染也逐渐增加，根据咱国家居民饮用水水质标准的形成以及管理，逐渐与国际饮用水标准要求相接轨，急需加强对饮用水水源的管理工作以及摸索一个适用于本市自来水厂的改革和技术革新的策略方法，并且探讨分析水厂供水管网卫生安全技术。本文对本市自来水厂生活饮用水公司的两个小区的主干线出口水和用户末梢水进行了水质指标检测与对比分析研究，揭示了饮用水在管网中水质发生变化的规律及原因。
