目的为全面掌握遵义市汇川区农村生活饮用水卫生状况,让农村村民饮水质量得到健康有效的保障,为政府制定决策措施提供科学依据。方法以遵义市汇川区农村饮用水水质监测点的水质作为监测对象,按照集中式供水点的抽样原则于2010~2012年度共检测236份农村饮用水水质。结果 2010~2012年度共检测农村饮用水水质236份,其中2010年检测水样104份,合格10份,合格率为9.62%,2011年检测水样52份,合格29份,合格率为55.77%,2012年检测水样80份,合格53份,合格率为66.25%。差异有统计学意义(χ2=68.86,P<0.05)。但是微生物检测项目里的总大肠菌群合格率仍然偏低,耐热大肠菌群和菌落总数的合格率在连续的三年里也不算每年都很高。结论提示遵义市农村饮用水受生活污水和粪便污染的现象还较普遍。因此,要加强水源选择、防护、水塔水池定期清洗和消毒制度等综合措施治理,消除饮用水安全隐患,防止介水传染病的发生。
The purpose is to fully grasp the health status of rural drinking water in Huichuan District of Zunyi City so that the drinking water quality of rural villagers can be guaranteed healthily and effectively and provide scientific basis for the government to make decision-making measures. Methods Taking the water quality of rural drinking water quality monitoring points in Huichuan District of Zunyi as the monitoring object, a total of 236 rural drinking water quality were tested in 2010-2012 according to the sampling principle of centralized water supply points. Results A total of 236 drinking water samples were collected from 2010 to 2012. Among them, 104 were tested for water samples in 2010 and 10 samples were passed. The pass rate was 9.26%. In 2011, 52 samples were tested and 29 samples were qualified. The pass rate was 55.77% In 2012, 80 samples were tested and 53 were qualified, with a pass rate of 66.25%. The difference was statistically significant (χ2 = 68.86, P <0.05). However, the total coliform passing rate in the microbiological testing project is still low, and the passing rate of the total number of heat-resistant coliform bacteria and colonies is not high every year for three consecutive years. Conclusions suggest that drinking water in rural Zunyi by domestic sewage and faecal contamination is still more common. Therefore, to strengthen the water source selection, protection, regular cleaning and disinfection of the water tower pool and other comprehensive measures to eliminate potential safety hazards in drinking water and prevent the occurrence of water-borne infectious diseases.
