摘要
目的了解成都市郫都区饮用水卫生状况和水质质量,及时掌握全区城乡饮用水卫生状况,保障全区居民饮用水安全。方法依据GB/T 5750-2006《生活饮用水标准检验方法》对2015-2017年成都市郫都区生活饮用水水样进行采集、保存和检测,按照GB 5749-2006《生活饮用水卫生标准》进行评价。采用SPSS 20.0统计软件进行相关统计分析。结果 2015-2017年共检测水样654份,合格582份,总体合格率为89.0%,市政供水、二次供水、乡镇供水及农村分散式供水水质总体合格率分别为100.0%、98.3%、88.7%和72.5%。枯水期合格率92.4%高于丰水期85.6%。地表水和地下水水质监测合格率分别为99.6%和83.3%。3年检测水样不合格项目主要为总大肠菌群、菌落总数、铁、锰。结论微生物指标超标是目前成都市郫都区饮水卫生安全的主要问题。农村饮用水合格率有待进一步提高,建议加大对农村集中式供水和互通工程的建设,保证全区居民饮用水安全。

Results A total of 654 water samples were tested for three years,and the qualified rate was up to 89.0% and the total qualified rate of municipal water supply,secondary water supply,centralized water supply and distributed water supply were 100.0%, 98.3%, 88.7% and 72.5%, respectively. The water qualities between surface water and ground water and those between dry and rainy seasons were significantly different(P<0.05). The qualified rates of 4 indicators,including total coliform group,total number of bacteria, Iron and manganese. Conclusion Microbial indicators exceeded the level of drinking water is currently the main problem of health and safety. Quality of drinking water in rural areas needs to be further improved.
