目的了解宁河县2011-2014年城镇及农村生活饮用水微生物污染状况,为城乡生活饮用水的卫生管理提供依据。方法对2011-2014年1769份生活饮用水水样按GB/T5750.12-2006《生活饮用水标准检验方法》进行检验,按GB5749-2006《生活饮用水卫生标准》进行结果评价。结果 2011-2014年宁河县城镇及农村生活饮用水卫生质量逐年提高,城镇集中供水各年份合格率分别为87.16%、92.86%、93.58%、96.97%;农村小型集中供水各年份合格率分别为82.47%、86.77%、87.31%、91.75%。结论城镇集中供水微生物指标合格率高于农村小型集中供水合格率,相关部门应继续加强城乡生活饮用水的卫生管理及管网改造工作,使人们的饮用水水质卫生得到更大的保障。
Objective To understand the status of microbial contamination of drinking water in urban and rural areas from 2011 to 2014 in Ninghe County and provide the basis for health management of drinking water in urban and rural areas. Methods 1769 drinking water samples from 2011 to 2014 were tested according to GB / T5750.12-2006 Standard Test Method for Domestic Drinking Water, and the results were evaluated according to GB5749-2006 Standard for Drinking Water Quality. Results From 2011 to 2014, the sanitary quality of drinking water in urban and rural areas of Ninghe County increased year by year. The passing rates of urban centralized water supply in each year were 87.16%, 92.86%, 93.58% and 96.97% respectively. The passing rates of rural small-scale centralized water supply were 82.47%, 86.77%, 87.31%, 91.75%. Conclusion The qualified rate of microbiological indicators for centralized water supply in urban areas is higher than the qualified rate of small centralized water supply in rural areas. Relevant departments should continue to improve the sanitary management of urban and rural drinking water and the renovation of pipe network so that people’s drinking water quality can be more protected.
