管道分质供水亦称管道直饮水,是指公共供水经过深度净化处理后,通过独立封闭循环管道直接供用户饮用的供水方式,属于集中式供水的一种形式[1]。此种供水形式自1997年在上海居民小区出现至今,已历经18年。为探究管道分质供水水质的影响因素,为更好地实施监督提供数据,保障居民饮用水卫生安全,本研究对2015年上海市闵行区管道分质供水的卫生及管理情况进行了调查。
Pipeline sub-quality water supply, also known as direct drinking water pipe, is a public water supply through deep purification, through independent closed loop pipeline directly for the user to drink water supply, is a form of centralized water supply [1]. This type of water supply has been in use for 18 years since its emergence in Shanghai’s residential area in 1997. In order to explore the influential factors of quality of water supply in pipelines, provide data for better supervision and ensure the health and safety of residents drinking water, this study investigated the health and management of sub-quality pipelines in Shanghai Minhang District in 2015.
