目的通过对三亚市近年来农村饮用水卫生监测,了解农村饮用水水质变化趋势,为改善农村饮用水水质提供可靠的科学依据。方法对三亚市2009～2011年5个乡镇有代表性的监测点,在丰水期、枯水期进行采样监测,根据《生活饮用水标准检验方法》(GB/T5750-2006)进行检测,依据《生活饮用水卫生标准》(GB5749-2006)标准进行结果评价。结果 2009～2011年共检测220份水样,总合格率为60.9%,其中,2009～2011合格率分别为48.6%,63.4%和75.6%,差异有统计学意义(χ2=14.04,P﹤0.01)。细菌学指标合格率仅为69.09%。5个乡镇水样检测合格率差异有统计学意义(χ2=16.42,P﹤0.01)。此外,丰水期、枯水期水样检测合格率,出厂水和末梢水水样检测合格率均无统计学意义。结论三亚农村生活饮用水合格率偏低,细菌学指标是影响本市农村饮水水质的重要因素,建议加强对饮水水源的监督监测力度,以保障农村居民的身体健康。
Objective To understand the trend of drinking water quality in rural areas by monitoring the health of rural drinking water in recent years in Sanya City and provide a reliable scientific basis for improving drinking water quality in rural areas. Methods The representative monitoring sites of 5 townships in Sanya from 2009 to 2011 were sampled and monitored during the wet season and the dry season. According to the Standard Test Method for Domestic Drinking Water (GB / T5750-2006) Drinking water health standards "(GB5749-2006) standards for evaluation of the results. Results A total of 220 samples were collected from 2009 to 2011, with a total pass rate of 60.9%. Among them, the pass rates from 2009 to 2011 were 48.6%, 63.4% and 75.6%, respectively, with statistical significance (χ2 = 14.04, P <0.01) ). Bacteriological indicators pass rate was only 69.09%. There was a statistically significant difference in the passing rate of water samples in 5 townships (χ2 = 16.42, P <0.01). In addition, wet season, dry season, water sampling pass rate, factory water and the water quality of the final test pass rate was not statistically significant. Conclusion The qualified rate of drinking water in rural areas in Sanya is low. Bacteriological indicators are important factors affecting the quality of drinking water in rural areas of this Municipality. It is suggested to strengthen supervision and monitoring of drinking water sources to ensure the health of rural residents.
