摘要
目的调查了解安宁市生活饮用水水质卫生状况,对2011年-2012年饮水监测结果进行分析,为提高生活饮用水卫生质量提供科学依据。方法依据《生活饮用水标准检验方法》(GB/T 5750-2006)检测。结果两年共检测水质873件,合格478件,总合格率为54.75%;2011年合格率50.13%,2012年合格率58.44%,合格率呈逐年上升趋势,差异有统计学意义(χ2=6.001,P<0.05);主城区集中式供水合格率95.19%,农村集中式供水合格率48.65%,差异有统计学意义(χ2=87.493,P<0.001);全市集中式供水合格率高于分散式供水,差异有统计学意义(χ2=42.481,P<0.001)。结论造成农村水质合格率偏低的原因涉及感官、化学和微生物指标共11个项目超标,应该加强饮水消毒和管理工作,有效预防介水传染病,切实保障全市人民群众饮水安全。
Objective To investigate the drinking water quality of Anning, and analyze the drinking water monitoring results from 2011 to 2012, so as to provide scientific basis for improving the quality of drinking water. Methods The water samples were detected in accordance with ＂Standard examination methods for drinking water （ GB/T 5750 - 2006）. Results Totally 873 water samples were detected in two years, 478 samples were qualified with the total qLtalified rate of 54.75% ; The qualified rates of water samples were 50.13% in 2011 and 58.44% in 2012, showing an increasing trend, and the difference had statisti- cal significance between two years（x2 = 6. 001, P 〈 0.05）. The qualified rate of centralized water supply was 95.19% in urban area and 48.65% in village, there was significant statistical difference between two areas （X2 = 87. 493, P 〈 0. 001 ） ; In the whole city, the qualified rate of centralized water supply was significantly higher than non - centralized water supply, and the difference had statistical significance（x2 = 42. 481, P 〈 0. 001 ）. Conclusion Eleven over - standard items, such as sensory index, chemical index and microorganisms has led to low qualified rate of water in rural area, thus the relevant departments should pay more attention to reinforce disinfection and perfect the water quality surveillance system to prevent water - borne com- municable diseases, so as to ensure the drinking water safety.
