摘要
[目的]掌握乡镇学校生活饮用水水质卫生状况,为学校饮水安全管理和工程建设提供科学依据。[方法]2009～2011年对高县乡镇学校饮用水进行监测,采样和实验室检测均按国家标准GB/T 5750-2006《生活饮用水标准检验方法》进行。[结果]2009～2011年合计检测水样470份,合格率为58.94%。2009～2011年高县乡镇学校饮水合格率分别为49.66%、57.59%和68.71%,各年间水质差异有统计学意义(P<0.01)。集中式和分散式供水合格率分别为66.06%、52.61%,差异有统计学意义(P<0.01)。[结论]高县乡镇学校饮水合格率呈逐年上升。集中式供水水质优于分散式,学校饮用水合格率较低,应加强监督管理。
[Objective]To obtain the information on the quality of drinking water in schools of townships,so as to pro- vide scientific bais for the safety management and project construction of drinking water in such schools. [Methods]The drinking water of townships schools of Gao county was sampled and tested during 2009-2011,in accordance with the GB/ T 5750-2006 National Standard on Method for Drinking Water Testing. [-Results]A total of 470 samples were tested with a pass rate of 58.94%. The pass rate of drinking water in township schools in Gao county during 2009-2011 was 49.66~, 57.59 ~ and 68.71 ~ respectively, and the difference of the water quality in different years was statistically significant （ P d0.01）. The pass rate of concentrated water supply and distributed water supply was 66.06% and 52.61~, and the difference was statistically significant （ P d0.01）. [Conclusion]The pass rate of drinking water of township schools in Gao county is rising year by year. The quality of concentrated water supply is better than that of distributed water supply. However,the pass rate Of drinking water of the schools is low and enhanced management should be practiced.
