摘要
目的了解寿光市农村学校生活饮用水水质卫生状况,为学校饮用水卫生监督和科学管理提供依据。方法于2009~2014年的4、8月份,对全市辖区内83所农村学校饮用水采样检测,对供水单位基本情况进行现场调查,采集各年度枯水期、丰水期的末梢水各1份,按GB/T 5750-2006《生活饮用水标准检验方法》进行采样和实验室检测,按GB5749-2006《生活饮用水卫生标准》进行评价。结果寿光市农村学校生活饮用水合格率为70.68%,各年份合格率呈逐年上升的趋势,2009年合格率最低53.01%,2014年合格率最高89.76%(P〈0.05)。集中式供水水样合格率为80.11%,分散式供水水质合格率为65.06%(P〈0.05)。枯水期水质合格率为62.05%,丰水期合格率为79.32%(P〈0.05);中学部合格率为69.59%,小学部水质合格率为71.56%(P〉0.05)。不同检测指标合格率不同,细菌总数、大肠菌群合格率最低,合格率分别为72.79%,73.49%细菌总数、大肠菌群合格率低于其他指标合格率(P〈0.05)。结论寿光市农村学校饮用水饮水合格率较低,受微生物污染严重。
