[目的]了解镇江市区长江不同断面饮水水源的水质卫生状况,分析其对居民生活饮用水水质卫生的影响,为确保群众生活饮用水安全卫生提供科学依据。[方法]对镇江市区上、下游不同断面二家集中式供水单位的长江水源水及其出厂水进行水质卫生监测与评价。[结果]长江饮用水源水的水质合格率为8.33%,不合格项目为铝、铁两个指标;出厂水的水质合格率为100.00%。2个断面饮用水源水质及出厂水质差异有统计学意义(P<0.01)。[结论]长江镇江段饮用水源水存在铝、铁的污染因素,通过制水工艺进行有效净化处理,能够达到生活饮用水卫生标准。
[Objective] To understand the sanitary status of drinking water sources in different sections of the Yangtze River in Zhenjiang City and analyze its impact on the sanitary quality of drinking water and provide a scientific basis for ensuring the health and safety of drinking water. [Method] The water quality sanitary monitoring and evaluation of the Yangtze River source water and its ex-factory water were conducted in two centralized water supply units with different sections in the upper and lower reaches of Zhenjiang City. [Result] The qualified rate of water quality of source drinking water in Yangtze River was 8.33%. The unqualified items were aluminum and iron. The qualified rate of water in factory water was 100.00%. The water quality of drinking water source and water quality of the two sections were statistically different (P <0.01). [Conclusion] There are aluminum and iron pollution factors in drinking water source of Zhenjiang section of Yangtze River, and the sanitary standard of domestic drinking water can be achieved through effective purification process.
