【摘要】：目的掌握罗平县农村饮用水安全工程水质卫生状况,为预防控制水性疾病和饮用水公共卫生事件提供可靠依据。方法根据《云南省农村饮用水水质卫生监测技术方案》的要求,按照《生活饮用水卫生标准检验方法》(GB/T5750-2006)进行水样采集和检测,《生活饮用水卫生标准》(GB5749-2006)进行结果评价。结果2011-2014年共检测供水点80个,各年检测20个供水点,检测水样320份,合格水样37份,合格率仅为11.6%。不合格项目主要为微生物指标,合格率枯水期为12.5%,丰水期为10.6%;合格率比较差异无统计学意义(χ~2=0.275,P0.05)。水源类型有地面水和地下水,其中地面水276份,地下水44份,微生物指标地面水合格率为3.3%,地下水合格率为63.6%,地下水合格率明显高于地面水(χ~2=50.833,P0.005);感官性状指标地面水合格率为77.5%,地下水合格率为100.0%,差异具有统计学意义(χ~2=12.250,P0.005)。一般化学指标地面水合格率为92.8%,地下水合格率为100.0%,差异无统计学意义(χ~2=3.401,P0.05)。结论罗平县农村饮用水微生物污染是主要的卫生问题。目前建设的农村安全饮水工程,只是改变了供水方式,供水未处理现象普遍存在,应引起有关部门的高度重视,建议加强对农村集中式供水的管理和监督。
[Abstract]:Objective to understand the water quality hygiene status of rural drinking water safety project in Luoping County, and to provide reliable basis for prevention and control of water-borne diseases and drinking water public health events. Methods according to the requirements of Yunnan Rural drinking Water Sanitation Monitoring Technical Scheme, water samples were collected and detected according to the Sanitary Inspection method for drinking Water (GB/T5750-2006). The results were evaluated by the Sanitation Standard for drinking Water (GB5749-2006). Results from 2011 to 2014, 80 water supply points were detected, 20 water supply points were detected in each year, 320 water samples were tested, 37 qualified water samples were qualified, and the qualified rate was only 11.6%. The unqualified items were mainly microbial indexes, the qualified rate was 12.5% in low water period and 10.6% in abundant water period, and there was no significant difference in qualified rate (蠂 ~ 2 / 0.275, P0.05). The qualified rate of surface water and groundwater is 3.3% and 63.6%, respectively. The qualified rate of groundwater is obviously higher than that of surface water (蠂 ~ 2 ~ 50.833, 蠂 ~ 2 ~ 50.833, P < 0.05), the qualified rate of ground water is 3.3%, and the qualified rate of groundwater is 63.6% (蠂 ~ 2 ~ 2 ~ 50.833). P0.005); The qualified rate of surface water and groundwater were 77.5% and 100.0% respectively. The difference was statistically significant (蠂 ~ 2, 12.250, P0.005). The qualified rate of surface water and groundwater were 92.8% and 100.0%, respectively. There was no significant difference (蠂 ~ 2 / 3.401, P0.05). Conclusion microbial contamination of rural drinking water in Luoping County is a major health problem. At present, the safe drinking water project in rural areas has only changed the way of water supply, and the phenomenon of unhandled water supply is widespread, which should be attached great importance to by the relevant departments, and it is suggested that the management and supervision of centralized water supply in rural areas should be strengthened.
