目的了解勐腊县农村生活饮用水卫生质量,掌握饮水水质、肠道传染病的动态变化情况,为制订科学、有效的改进措施提供依据。方法采用分层随机抽样方法,对农村生活饮用水水质按GB/T5750-2006进行抽样检测,按标准GB5749-2006进行评价。结果饮用水中微生物污染较严重,菌落总数、总大肠菌群、耐热大肠菌群合格率分别为55.7%、17.7%、18.8%,枯水期低于丰水期(菌落总数χ2=2.65,P>0.05;大肠菌群χ2=9.15,P<0.05;粪大肠菌群χ2=11.08,P<0.05)。结论我县农村生活饮用水水质不容乐观,存在安全隐患,需严格管理,防止肠道传染病的发生。
Objective To understand the sanitary quality of rural drinking water in Mengla County and to grasp the dynamic changes of drinking water quality and intestinal infectious diseases so as to provide basis for making scientific and effective improvement measures. Methods By stratified random sampling method, the quality of rural drinking water was sampled according to GB / T5750-2006 and evaluated according to GB5749-2006. Results The microbial contamination in drinking water was more serious. The total number of colony, total coliforms and heat-resistant coliform were 55.7%, 17.7% and 18.8%, respectively. The dry season was lower than the wet season (total number of colony χ2 = 2.65, P> 0.05; coliform χ2 = 9.15, P <0.05; fecal coliform χ2 = 11.08, P <0.05). Conclusion The water quality of drinking water in rural areas in our county is not optimistic, there are potential safety problems, which need to be strictly managed to prevent the occurrence of intestinal infectious diseases.
