龙岩市2类市政供水水质质量分析

Analysis of the 2 Types Municipal Supply Water Qualityin Longyan City

目的为保障居民健康和生命安全,动态了解龙岩市2类市政供水水质质量状况。方法对2003-2013年市政供水的进厂、出厂和末梢水样进行监督监测。结果 11年来市政供水的进厂、出厂水合格率均值100.0%。末梢水合格率98.5%,其中水库末梢水合格率87.3%。用户反映时有"黄水"出现,经检测主要是水中的铁、色度、浑浊度超标。结论末梢水合格率下降的主要原因是启用水库水后,其低pH低硬度的水易腐蚀老化的管道,导致"黄水"出现,不容乐观。通过管网改造、提高水质pH值基本得以控制,但必须加快建立饮用水水源地实时监测监控系统,加强水质监控,提高供水水质。

Objective In order to master the 2 kind of municipal water supply and its quality condition in Longyan dynamic,ensuring people＇s health and life safety. Methods We supervised and inspected the municipal water according,which into and out of the factory,the peripheral water conduct from 2003 to2013 in longyan. Results In these 11 years,the municipal water supply into and out of the factory the average qualified rate of 100.0%. The water peripheral qualified rate of 98.5%,with reservoir water peripheral water percent of 87.3%.The user you have ＂including＂ appear to reflect,is mainly detected by excess iron,chromaticity and turbidity of the water. Conclusions The main reason for decline in peripheral water percent of pass is to enable the reservoir water,the low p H of water of low hardness easy aging pipeline corrosion,leading to ＂including＂ appear. That is not optimistic. It can be control through the network transformation and improving the water p H value,but it must speed up by building the drinking water real-time monitoring system in water source,strengthening the water quality monitoring,improving the quality of water supply.
