摘要
目的了解2016年黄山市农村生活饮用水水质卫生状况,为改善农村饮用水水质提供科学依据。方法以全市涉农县(区)的80%乡镇为监测点,按照GB/T 5750-2006《生活饮用水标准检验方法》中有关规定进行水样采集、保存和检测。按照GB 5749-2006《生活饮用水卫生标准》进行评价。结果 2016年黄山市水质合格率为51.7%,去除微生物指标后合格率为90.8%。出厂水合格率为52.6%,末梢水为51.0%,差异无统计学意义(χ~2=0.122,P>0.05);地面水水质合格率为55.9%,高于地下水为30.8%,差异有统计学意义(χ~2=16.46,P<0.01);丰、枯水期水质合格率分别为49.6%、53.8%,差异无统计学意义(χ~2=0.85,P>0.05)。不合格指标中总大肠菌群的合格率最低(57.1%)。结论黄山市农村生活饮用水水质合格率偏低,存在较大安全隐患,应完善消毒设施,强化消毒工艺,杀灭水中微生物,以有效提高农村饮用水水质合格率。
[Objective] To understand the hygiene situation of drinking water quality in rural areas of Huangshan City in 2016,and provide scientific basis for improving the quality of drinking water in rural areas.[Methods]There were 80% towns of all agricultural counties（districts） in Huangshan city for monitoring points. The water samples were collected,saved and detected according to GB/T 5750-2006＂standard examination methods for drinking water＂,and evaluated according to GB 5749-2006＂drinking water health standards＂.[Results]The qualified rate of water quality was 51.7% in Huangshan City in 2016,and the qualified rate was90.8% after removal of microbial index. The qualified rate of finished water was 52.6%,pipe water was 51.0%,and the difference was not statistically significant（χ~2=0.122,P〉0.05）. The qualified rate of surface water was 55.9%,ground water was 30.8%,and the difference was statistically significant（χ~2=16.46,P〉0.01）. The qualified rates of wet season and dry season were 49.6% and 53.8% respectively,and the difference was not statistically significant（χ~2=0.85,P〉0.05）. Among unqualified index,the qualified rate of total coliform group was the lowest（57.1%）.[Conclusion]The qualified rate of drinking water in rural areas of Huangshan City was relatively low,which had major security risks. We should improve the disinfection facilities,strengthen the disinfection process and kill microorganisms in water to effectively improve the qualified rate of drinking water quality in rural areas.
