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 To ensure the health and life safety of residents, to dynamically understand the quality of water quality in two types of municipalities in Longyan. Methods The municipal water supply into the factory, factory and peripheral water samples from 2003 to 2013 were supervised and monitored. Results 11 years of municipal water supply into the plant, the average passing rate of manufactured water 100.0%. Peripheral water pass rate of 98.5%, of which the reservoir end of the pass rate of 87.3% water. When users reflect “yellow water” appears, the test is mainly iron in the water, color, turbidity exceeded. Conclusions The main reason for the decline of the qualified rate of the peripheral water is that the water with low pH and low hardness easily corrodes after the reservoir water is activated, resulting in the emergence of “yellow water”, which is not optimistic. Through the transformation of the pipe network, to improve the basic pH control of water quality, but must speed up the establishment of real-time monitoring and control system of drinking water sources to strengthen water quality monitoring, improve water quality.
