摘要:目的  了解南平市生活饮用水水质卫生状况,保障民众饮水卫生与安全。方法  依据《生活饮用水卫生标准》(GB 5749 - 2006)对2010—2013年该市城区与农村的生活饮用水3 677份水样监测结果进行分析评价。 结果  2010—2013年共抽检城区水厂出厂水样228份,平均合格率82.89%,其中2010—2013年合格率分别为85.09%、72.88%、87.93%和85.97%。2011年合格率较低,不合格指标主要为pH值、铁、锰、铝和微生物。抽检城区末梢水717份,合格率73.92%,各年份合格率分别为71.20%、57.72%、93.82%和87.93%,呈上升趋势,不合格指标主要为游离余氯、pH值、铁、锰和微生物,不同年份合格率差异有显著统计学意义(χ2 = 89,P < 0.01)。抽检农村饮水安全工程水样2 732份,合格率37.23%,各年份合格率分别为30.00%、38.26%、37.02%和45.45%,呈明显上升趋势,不合格指标主要为游离余氯、pH值、铁、锰和微生物,不同年份水样合格率差异有统计学意义(χ2 = 26.56,P < 0.05)。城区水厂出厂水水质合格率(82.89%)明显高于农村饮水安全工程水质合格率(37.23%,χ2 = 181.79  P < 0.01)。结论  目前南平市城区生活饮用水水质基本符合GB 5749—2006要求,微生物污染是农村饮水安全工程水质合格率较低的主要原因,应加强农村饮水安全工程建设,加强卫生管理和监督力度,同时预防控制生活饮用水的微生物污染,保障民众饮用水的卫生安全。

Abstract: Objectives To understand the hygienic quality of drinking water in Nanping city, to protect the safety of drinking water. Methods Based on Standards for Drinking Water Quality (GB5749-2006), the result of 3677 drinking water samples monitored in 2010-2013 were analyzed and evaluated. Results The average pass rate of 228 finished water samples collected from waterworks in the city was 82.89%, and the pass rate in 2010, 2011, 2012 and 2013 was 85.09%, 72.88%, 87.93 and 85.97%, respectively. The unqualified indexes were pH, iron, manganese, aluminum, and micro-organisms. The average pass rate of 717 peripheral water samples in the urban area was 73.92%, and the pass rate in each year was 71.20%, 57.72%, 71.2% and 87.93%, respectively; the unqualified indexes were free residual chlorine, pH, iron, manganese and micro-organisms.  The average pass rate of 2,732 water samples collected from rural drinking water safety projects was 37.23%, and the pass rate in each year was 30.00%, 38.26%, 30% and 45.45%, respectively, which was improved in an upward trend; the unqualified indexes were free residual chlorine, pH, iron, manganese and micro-organisms.  The difference of pass rate in different years was statistically significant (χ 2 = 26.56, P < 0.05).  The quality of water from urban waterworks (82.89%) was higher than that from rural drinking water safety projects (37.23%, χ2=181.79, P < 0.01). Conclusion The quality of drinking water in Nanping city could meet the requirement of GB/5749-2006; the main reason of lower water quality in rural drinking water safety projects was microbial contamination.  The construction of rural drinking water safety projects should be strengthened. Strengthening hygienic management and supervision, prevention and control of microbial contamination of drinking water, to safeguard the safety of public drinking water.
