目的 了解2017年兰州市城市饮用水水质卫生状况。方法 2017年简单随机(随机数字法)选择兰州市84个城市饮用水监测点采集168份水样进行水质分析。结果 168份水样合格率为78.0%131/168);水样合格率,地下水为56.3%18/32),低于地表水83.1%113/136),(χ2=10.865P<0.05)。丰水期和枯水期比较,水源水、出厂水和末梢水比较,差异均无统计学意义。33项检测指标合格率在91.7%~100.0%,以浑浊度合格率最低;不同水样中,地下水硝酸盐氮、氯化物、硫酸盐、溶解性总固体和总硬度的合格率(87.5%93.8%87.5%81.3%65.6%)低于地表水(均100%),(χ2值分别为12.4524.11012.45221.28044.565P<0.05)。结论 兰州市城市饮用水水质总体良好,感官性状和一般化学指标是影响水质的重要原因。

Objectives To understand the sanitary situation of urban drinking water quality in Lanzhou. Methods 84 drinking water monitoring sites were selected randomly and 168 water samples were collected and analyzed in Lanzhou in 2017. Results The qualified rate of 168 water samples was 78.0%. The qualified rate of groundwater (56.3%) was lower than that of surface water (83.1%), (χ2=10.865, P<0.05). There was no significant difference between the qualified rate of wet season and dry season, and there was also no significant difference among the qualified rate of source water, finished water, and terminal piped water. The range of qualified rate of 33 detection indexes were from 91.7% to 100.0%, of which turbidity was the lowest. The qualified rate of nitrate nitrogen, chloride, sulfate, total dissolved solids, and total hardness of groundwater were 87.5%, 93.8%, 87.5%, 81.3%, and 65.6%, respectively; which were lower than that of surface water (100.0%), (χ2=12.452, 4.110, 12.452, 21.280, 44.565, P<0.05). Conclusions The quality of urban drinking water in Lanzhou is generally good. Sensory properties and general chemical indexes are important factors affecting the water quality.
