|
摘要
目的了解龙口市农村集中式供水水质卫生状况,为改善农村饮用水水质提供可靠依据。方法 2017年7—8月,按照GB/T 5750-2006《生活饮用水标准检验方法》对所采集的462份水样进行检测和分析。结果共检测样品462份,合格322份,合格率69.70%;净化设备总体安装率为81.17%,有净化设备水样合格率83.73%,无净化设备水样合格率9.19%,差异有统计学意义(χ~2=185.765,P<0.01);合格率较低的指标主要是硝酸盐、菌落总数、总大肠菌群、耐热大肠菌群和大肠埃希菌,合格率分别为83.77%、84.42%、85.50%、89.18%和95.89%。结论龙口市农村生活饮用水总体卫生状况尚需完善,应推进农村改水建设,配齐饮用水净化设备,规范消毒措施。
[Objective] To understand the quality of drinking water derived from rural centralized water supplies in Longkou City,provide scientific basis to improve the quality of the rural drinking water. [Methods] From July to August in 2017, 462 water samples were detected and analyzed in accordance with the Standard test me thod for drinking water(GB/T 5750-2006).[Results] A total of 462 samples were detected, 322 were qualified with the qualification rate of 69.70%. The installation rate of water purification equipment was 81.17%. The qualification rate of water samples with purification equipment was 83.73%,while that of water samples without purification equipment, and the difference was statistically significant(χ~2=185.765,P<0.01). The items with lower qualification rate included nitrate,total colony, total coliforms,Thermotolerant coli and Escherichia coli,which the qualification rate was 83.77%, 84.42%, 85.50%, 89.18% and 95.89%, respectively. [Conclusion]The quality of drinking water needs to be improved in the rural areas of Longkou City, by advancing the construction of rural water supply, equipping purification equipment fully, and standardizing procedures of disinfection.
