摘　　要：目的了解桂林市农村集中式供水工程水质微生物污染状况,为改善农村集中式供水丰水期水质卫生及其安全监管提供科学依据。方法对2015年桂林市11个县2个城区的农村集中式供水的丰水期出厂水和末梢水进行采样,对水样微生物指标(菌落总数、总大肠菌群、耐热大肠菌群和大肠埃希氏菌)进行监测,按照GB/T 5750-2006《生活饮用水标准检验方法》进行检测。结果丰水期共检测集中供水水样527份,出厂水243份,微生物指标合格117份,合格率为48.15%;末梢水284份,微生物指标合格135份,合格率为47.54%。结论桂林市集中式供水水质合格率较低,应加强水源水的卫生防护,进一步完善水净化消毒工艺和设施,大力开展饮水卫生宣教,保障农村居民饮水安全。Objective To understand the status of the centralized water supply engineering quality of microbial contamination in Guilin,in order to improve the rural centralized water supply plentiful water quality will provide a scientific basis for health and safety regulation. Methods 2 city of Guilin in 2015 11 county rural centralized water supply water period of finished water and tap water samples,water samples of microbial indicators（ total bacteria,total coliform,thermo tolerant coliform bacteria and Escherichia coli） monitoring. According to GB/T 5750-2006 ＂standard examination methods for drinking water＂were detected. Results During the full water period,527 samples of centralized water supply were tested,243 of which were manufactured and 117 of which were qualified. The qualified rate was 48. 15%. 284 pieces of peripheral water,135 qualified microbiological indicators,and the passing rate was 47. 54%. Conclusion The low pass rate of centralized water supply in Guilin City,we should strengthen the health protection of water sources,improve water purification and disinfection technology and facilities,vigorously carry out health education of drinking water,rural residents to protect the safety of drinking water.
