摘要:

目的:了解大理市2010年至2013年生活饮用水卫生微生物污染状况,为水质卫生监督及管理提供科学依据。方法:抽
取大理市15个乡镇有代表辖区的监测点,每年于枯水期、丰水期采集水样2次,按照GB/T 5750—2006《生活饮用水标准检验方
法》进行水样的采集、检测,按《生活饮用水卫生标准》(GB 5749—2006)进行卫生微生物学评价。结果:2010年至2013年总共
检测水样1 996份。3种水源类型微生物指标检测结果的差异具有统计学意义(χ2=11.999,P<0.05),2010年至2013年丰水期水
样不合格率(43.76%)明显高于枯水期(11.64%),χ2=81.130,P<0.05。结论:大理市2010年至2013年生活饮用水均受到了不同
程度的微生物污染,总合格率有逐年上升的趋势,但合格率并不高,水质问题亟需改善。

Abstract:

Objective:To investigate the microbial contamination of drinking water in Dali from 2010 to 2013, to provide scientific
basis for the surveillance and management of drinking water. Methods:Water samples were collected in dry season and rainy season
twice a year from 15 representative jurisdiction monitoring sites of Dali which were randomly selected. The samples were collected and
tested according to GB/T 5750—2006, and sanitary microbiology evaluation followed GB 5749—2006. Results:Over the period from
2010 to 2013 1 996 water samples were collected and tested. The differences among three types of water test dimension were statistically
significant(χ2=11.999, P<0.05). Over the four years failure rate(43.76%) in rainy season was significantly higher than that
(11.64%)in dry season(χ2=81.130, P<0.05). Conclusion:The drinking water in Dali from 2010 to 2013 is inordinately polluted by
microorganism to somewhat different extent. Though the qualified rate has an ascending trend year by year, yet it is still low. So water
quality needs to be further improved.
