摘要
目的通过分析驻京某部队2012-2014年二次供水水质卫生监测资料,了解驻京某部队二次供水水质卫生状况,为加强部队二次供水的综合管理和改善水质提供科学依据。方法按照GB/T 5750-2006《生活饮用水标准检验方法》对驻京某部队二次供水和市供自来水进行水样采集和相关指标检测,2种供水水样分别为218份和180份,按照GB 5749-2006《生活饮用水卫生标准》判断各项指标的超标情况。结果 2012-2014年驻京某部队二次供水的总合格率为82.6%,其中总大肠菌群、硝酸盐氮和细菌总数的合格率相对较低,分别为92.3%、93.6%和94.9%。2012、2013及2014年二次供水的合格率分别为61.3%、88.7%、84.5%,2012年明显低于2013和2014年(P<0.05);二次供水和市供自来水相比,各年间的水质差异均无统计学意义(P>0.05)。二次供水的丰水期和枯水期水质合格率差异有统计学意义(P<0.05)。结论驻京某部队的二次供水近2年水质状况总体良好,但部分指标超标问题仍较突出,需要进一步改善。
Objective By analyzing inspection data of secondary water quality in some troops stationed in Beijing from 2012 to 2014, to understand sanitation of secondary water supply in troops in Beijing, so as to provide a scientific basis for strengthening the integrated management of secondary water supply of the forces, and to improve water quality. Methods The secondary water（218 samples） and municipal water（ 180 samples） of the troops stationed in Beijing were collected and detected according to ＂ Drinking Water Standard Test Method＂ （ GB / T 5750-2006） , and determined exceedances of the indicators according to ＂Drinking Water Health Standards＂ （GB 5749- 2006） . Results The total qualified rate of all the secondary water samples tested was 82.6%. The qualified rates of total coliforms （92.3%）, nitrate nitrogen （93.6%） and total bacteria （94.9%） were relative low. The qualified rates of secondary water were 61.3%, 88.7%, and 84.5% in 2012, 2013, and 2014 respectively, which in 2012 was significantly lower than those in 2013 and 2014 （ P 〈 0.05 ）. There was no statistical significance between secondary water and municipal water（ P 〉0.05 ）. There was statistical significance between wet and dry seasons about the qualified rate of secondary water（ P 〈 0.05 ）. Conclusion Water quality of secondary water is generally good in recent two years in the troops stationed in Beijing, but some measures should be taken to be further improve water quality of secondary water .
