摘　　要：目的对石家庄市2014—2021年生活饮用水常规指标进行监测,分析水质及主要监测指标变化趋势。方法收集整理2014—2021年石家庄市生活饮用水监测资料,分析生活饮用水合格率、主要监测指标合格率、主要监测指标变化趋势。结果2014—2021年石家庄市共监测水样10529份,总合格率为77.15%;地表水合格率(99.08%)高于地下水(75.96%)、城市水合格率(85.17%)高于农村水(75.05%)、枯水期合格率(79.79%)高于丰水期(74.51%),完全处理水合格率(99.10%)高于仅消毒(86.29%)和未处理(70.70%)(P均<0.05)。2014—2021年石家庄市生活饮用水最低合格率为69.49%,最高合格率为82.28%,总合格率呈上升趋势(P<0.05)。主要指标耐热大肠菌群、菌落总数、总硬度、硝酸盐、硫酸盐的合格率均呈上升趋势(P<0.05),菌落总数、硝酸盐、氟化物、总硬度、溶解性总固体、硫酸盐、氯化物的含量均呈下降趋势(P<0.05)。结论石家庄市2014—2021年生活饮用水水质整体呈现优化趋势,微生物指标仍是影响水质的主要因素。Objective To monitor the routine indicators of drinking water and to analyze the trend of water quality as well as main indicators in Shijiazhuang from 2014 to 2021.Methods The monitoring data of drinking water in Shijiazhuang from 2014 to 2021 were collected,and the qualified rate of drinking water and main indicators and the trend of main indicators were analyzed.Results A total of 10529 water samples were monitored in Shijiazhuang and the total qualified rate of drinking water was 77.15%from 2014 to 2021.The qualified rate of surface water(99.08%),urban water(85.17%)and drought period(79.79%)were higher than that of underground water(75.96%),rural water(75.05%)and rainy period(74.51%),respectively,while the qualified rate of completely treated water(99.10%)was higher than that of only sterilized water(86.29%)and untreated water(70.70%)(P<0.05).The lowest qualified rate was 69.49%,the highest qualified rate was 82.28%,and the total qualified rate showed an upward trend(P<0.05).The qualified rates of main indexes including heat-resistant coliforms,the total number of colonies,the total hardness,the content of nitrate and the content of sulfate showed an increasing trend respectively(P<0.05),while the contents of total colony,nitrate,fluoride,total hardness,soluble total solids,sulfate and chloride showed a decreasing trend respectively(P<0.05).Conclusion The overall quality of drinking water in Shijiazhuang city showed an optimization trend from 2014 to 2021,and microbial indexes were still the main factors affecting water quality.
