2002年广西部分农村饮用水卫生学调查

Sanitary Investigation on Drinking Water in Some Areas of Countryside in Guangxi,2002

目的了解农村饮用水卫生状况。方法选择广西9个县开展水源类型、供水方式的调查,每个县设10个采样点,共采集水样91份进行水质分析,按《农村实施(生活饮用水卫生标准)准则》进行评价。结果9个县人口的15.33%以地面水为水源,84.67%以地下水为水源,43.16%饮用集中式供水,10.57%和2.96%饮用经沉淀过滤的集中式饮用水和经消毒的集中式饮用水。集中式供水人口的68.66%饮用未经任何处理的饮用水。91份水样完全合格率为20.88%,其中地面水、地下水合格率分别为14.81%和23.44%,集中式和分散式给水细菌学指标合格率分别为32.61%和20.00%。结论被调查的9个县大部分农民还未饮上安全卫生的饮用水,且主要卫生问题是饮用水被微生物污染。

Objective To understand the status of the sanitary quality in some areas of countryside in Guangxi. Methods The investigation on the type of water source and the water supply was carried out in 9 counties.10 sampling points were established in each observed county.91 water samples were collected totally for the measurement of water quality ,then their sanitary quality was assessed based on the Criteria for Implementing the Hygienic Standards for Drinking Water in Countryside. Results In the observed 9 counties ,15.33% of total population drank water supplied with surface water,and 84.67% with ground water source. Drinking water from centralized water supply system was supplied to 43.16% of total population.In the centralized water supply system,the finished water completely treated by sedimentation and filtration was supplied to 10.57% of the total population,the disinfected finished water was only supplied to 2.96% of the total population,the raw water was directly supplied to 68.66% of the tap water-supplied population without any treatment.The completely-qualified rate of water samples was 20.88% for total 91 water samples,14.81% for surface water samples and 23.44% for ground water samples respectively.The qualified rate of bacterial indexes was 32.61% for water samples collected from centralized water supply system and 20.00% for those from decentralized water supply system. Conclusion Most of the peasants in the investigated 9 counties hadn't been supplied by safe and health drinking water.Contamination of drinking water by microorganisms was the main sanitary problem in water supply in countryside of Guangxi.
