目的 :调查生活饮用水中的微生物含量,为饮用水水质控制提供依据。方法 :回顾性分析我市2013~2015年的生活饮用水水质微生物污染结果,根据《生活饮用水卫生规范》进行细菌学检测及评价。结果 :我市2013~2015年的生活饮用水水质微生物检测合格率依次为87.5%、90.0%、91.2%,2015年生活饮用水水质微生物检测合格率显著高于2013年、2014年水平,差异具有统计学意义(P<0.05)。其中,县城水厂供水合格率为95.5%,二次供水合格率为95.6%,乡镇集中式供水和分散式供水合格率分别为87.1%和90.9%。乡镇集中供水微生物检测合格率显著低于县城供水、二次供水、分散式供水,差异具有统计学意义(P<0.05)。结论 :我市2013~2015年的生活饮用水微生物检测合格率偏低,尤其是农村地区的供水水质有待提高。
Objective: To investigate the microbial content in drinking water and provide the basis for drinking water quality control. Methods: The results of microbial contamination of drinking water quality in our city from 2013 to 2015 were retrospectively analyzed. Bacteriological examination and evaluation were carried out according to the Code of Hygienic Drinking Water. Results: The qualified rate of microbial detection of drinking water quality in our city from 2013 to 2015 was 87.5%, 90.0% and 91.2% respectively. The passing rate of microbial detection of drinking water quality in 2015 was significantly higher than that of 2013 and 2014, Statistical significance (P <0.05). Among them, the county water supply rate of 95.5% for waterworks, secondary water supply 95.6% pass rate, township centralized water supply and decentralized water supply pass rates were 87.1% and 90.9%. The qualified rate of micro-organism detection of centralized water supply in township was significantly lower than that of county water supply, secondary water supply and distributed water supply, with significant difference (P <0.05). Conclusion: The passing rate of drinking water microbes in our city from 2013 to 2015 is low, especially in rural areas.
