目的掌握2011年郧县生活饮用水水质状况,分析影响饮用水质量的因素。方法于2011年6月份对城区、乡镇、村级集中式供水点132份末梢水进行监测。结果 132份末梢水合格67份,合格率为50.76%;县、乡、村集中式供水末梢合格率分别为91.67%、44.74%、47.56%,县级分别高于乡镇(χ2=8.152,P=0.004)和村级(χ2=8.178,P=0.004)。微生物指标超标是水质不合格的主要原因。结论郧县乡镇和村级集中式供水水质较差,微生物超标为主要原因,应重点加强乡镇和村级集中式供水管理。
Objective To master the quality of drinking water in Yun County in 2011 and analyze the factors affecting the quality of drinking water. Methods In June 2011, 132 peripheral water samples of centralized water supply points in urban areas, townships and villages were monitored. Results The results showed that the qualified rate of water supply was 132.7%, and the pass rate was 50.76%. The passing rate of centralized water supply at county, township and village was 91.67%, 44.74% and 47.56% respectively, and the county level was higher than township (χ2 = 8.152, P = 0.004) and village level (χ2 = 8.178, P = 0.004). Microbial indicators exceeded the main reason for water quality failure. Conclusion In Yunxian townships and villages, the centralized water supply quality is poor and the microorganisms exceed the standard, which is the main reason. Emphasis should be placed on strengthening the centralized water supply management at villages and townships.
