摘要
目的:了解牟定县农村改水细菌学现状,提供农村改水技术支持,达到饮用安全生活饮用水的目的。方法:对2009年牟定县农村改水现场调查,采集水样并按照中华人民共和国《生活饮用水标准检验方法》和中华人民共和国《生活饮用水卫生标准》对水样进行检验和结果判定。结果:2009年牟定县农村改水微生物指标总不合格率为62.5%,其中细菌总数单项不合格率为18.8%,总大肠菌群单项不合格率为62.5%;水源30m以内有无污染源,其污染程度具有统计学意义。结论:2009年牟定县部分农村改水微生物超标,有导致肠道传染病暴发流行的隐患,政府应加快农村供水设施建设,加强对饮用水源的卫生防护,以保障农村居民饮水卫生。
Objective: To understand the hygienic bacteriology indicants of water improvement at Mouding County and provide technical supports for rural water improvement and obtain safe and healthy drinking water.Methods: Field investigation of water improvement at Mouding County was hold in 2009;total 32 water samples were collected and tested according to Standard Testing Methods for Drinking Water of China(GB/T5750-2006).Results: The fraction defective of hygienic bacteriology indicants was 62.5%,in which the fraction defective of general bacterial population was 18.8% and the fraction defective of general coli group was 62.5%.There were significant differences on the degree of pollution between water sources of pollutants and no pollutants within 30 meters.Conclusion: The hygienic bacteriology indicants of water improvement exceed standard at part areas of Mounding county,which is likely to led to outbreaks of intestinal infectious diseases.Therefore government should speed up the building of rural water supply facilities to strengthen the health protection of drinking water sources and ensure drink water safely and wholesomely at rural residents.
