2011-2015年神农架林区农村饮用水监测结果分析

Analysis of rural drinking water monitoring results from 2011 to 2015 in Shennongjia

目的了解神农架林区农村饮用水水质状况,对2011-2015年神农架林区农村饮用水监测结果进行分析。方法采集2011-2015年枯水期和丰水期水样,按照《生活饮用水标准检验方法》(GB/T 5750-2006)[1]进行检测,按照《生活饮用水卫生标准》(GB/T 5749-2006)[2]进行结果评价分析。结果 2011-2015年共监测农村饮用水517份,合格水样224份,合格率为43.57%;不同年份间水质合格率比较差异无统计学意义(χ~2=5.45、P>0.05);枯水期和丰水期合格率有显著性差异(χ~2=13.68、P<0.01),出厂水与未梢水合格率也有显著性差异(χ~2=100.88、P<0.01)。结论神农架林区农村饮用水水质卫生差,合格率低,应改善集中式供水单位的水质消毒净化设施,加强水源地的保护和管理,加强日常卫生监督检测,确保农村饮用水安全。

Objective To understand the drinking water quality in rural areas of Shennongjia and analyze the rural drinking water monitoring results from 2011 to 2015. Methods The water samples in wet seasons and dry seasons were collected annually according to ＂Standard inspection method for drinking water＂（GB/T 5750-2006）, For resulted and analyzed according to ＂Drinking water health standards＂（GB/T 5749-2006）. Results drinking water in rural areas were monitored for 517 samples from 2011 to 2015,and qualified 224 samples,The total pass rate was 43.57 % .The annual qualified rates were no significant differences （X^2=5.45 ,P 〉0.05）,and the qualified rates had significant differences between dry seasons and wet seasons （X^2=13.68.P〈0.01）,and the qualified rates had significant differences between the factory water and tip water （X^2=100.88,P〈0.01）. Conclusion The rural drinking water quality in Shennongiia is poor, We should clean our centralized water disinfection and purification facilities,and Water source protection and management should be strengthened ,the water quality monitoring should be strengthened to ensure the safety of rural drinking water.
