目的了解烟台市牟平区农村生活饮用水的卫生状况,为今后农村改水提供依据。方法对城区外所有已安装集中式供水的村庄未梢水,按GB 5750-2006生活饮用水标准检验方法,对感官性状和一般化学指标、毒理指标、微生物指标的19个项目进行检测。结果 420份水样中合格率为41.67%。水样中菌落总数不合格率为24.05%,总大肠菌群不合格率为37.38%,氟化物不合格率为3.33%,硝酸盐不合格率为13.57%,总硬度不合格率为0.71%,肉眼可见物不合格率0.95%,锌不合格率0.48%,锰不合格率0.24%,铁不合格率为0.48%。结论烟台市牟平区农村集中式供水的水源污染严重,水源保护差,缺乏有效的消毒措施,须强化供水村管理,扩大饮水安全宣传,预防性卫生监督到位以改善目前状况。
Objective To understand the sanitary status of rural drinking water in Muping District of Yantai Municipality and provide the basis for future rural water improvement. Methods Nineteen projects of sensory traits, general chemical indicators, toxicological indicators and microbial indicators were tested for all the villages outside the urban area where no centralized water supply was installed. According to the standard test method of domestic drinking water of GB 5750-2006, Results The pass rate in 420 water samples was 41.67%. The total number of colony in water samples was 24.05%, the total coliform group was 37.38%, fluoride was 3.33%, nitrate was 13.57%, total hardness was 0.71% The naked eye can see the unqualified rate of 0.95%, zinc unqualified rate of 0.48%, manganese unqualified rate of 0.24%, iron unqualified rate of 0.48%. Conclusion The rural centralized water supply in Muping District of Yantai Municipality is seriously polluted by water.
