摘要
目的了解武汉市城市生活饮用水水质卫生状况,预防水源性疾病。方法根据《武汉市城市生活饮用水监测方案》设置出厂水、管网末梢水和二次供水监测点和监测频率。监测指标按照《生活饮用水标准检验方法》(GB/T5750-2006)进行检测,监测结果依据《生活饮用水水质卫生标准》(GB 5749-2006)进行评价。结果 2015年-2017年,武汉市城市生活饮用水合格率为97. 3%,其中出厂水、管网末梢水、二次供水合格率分别是为99. 6%、97. 2%和97. 0%。中心城区生活饮用水合格率高于新城区;水质不合格指标主要是菌落总数和游离余氯。结论武汉市城市生活饮用水水质总体情况较好,新城区二次供水存在安全隐患,相关管理部门和监管单位要加强水质卫生管理,保障生活饮用水的卫生安全。
Objective To understand the hygienic status of drinking water quality in Wuhan to prevent and control water-borne infectious diseases. Methods To set monitoring points and monitoring frequency of factory water,pipe network tip water and secondary water according to the Scheme of Drinking Water Surveillance in Wuhan City;The samples were tested according to the Standard Examination Methods for Drinking Water( GB/T 5750-2006),and the test results were evaluated by the Standards for Drinking Water Quality( GB 5749-2006). Results The qualification rates of drinking water were 97. 3% during 2015-2017,and that of finished water from water plants,tap water and secondary water supplies were 99. 6%,97. 2% and 97. 0%,respectively. The qualification rate of drinking water supply in urban area was better than new district. The unqualified indexes were the total counts of bacteria and free chlorine. Conclusion The overall situation of urban drinking water in Wuhan is relatively good,only a few potential security risks existed in the secondary water supply in the new urban area. Water quality health management should be strengthened to improve the quality of water supply and to ensure the safety of drinking water.
