吉林省农村饮用水现状及防治对策研究

Status and Control Countermeasures of Rural Drinking Water in Jilin Province

目的保障吉林省农村居民身体健康和生命安全,为制定本省农村饮用水安全发展规划及社会主义新农村建设规划提供科学依据。方法以绿园区为调查点,下发农村饮用水与环境卫生调查表,组织专业人员调查;随机选取10个村作为水质检测点,采集双份水样并检测14项水质指标。结果分散式供水覆盖人口占农村总人口数的97.17%,集中式供水占2.83%;10个检测点水质按《生活饮用水卫生标准》(GB 5749-2006)和其中的《农村实施<生活饮用水卫生标准>准则》进行综合评价,一级2个、二级1个、三级1个、超三级6个。结论吉林省(以绿园区为例)农村主要供水方式仍然以分散式供水为主;生活饮用水水质合格率偏低,总硬度、总大肠菌群数、细菌总数超标明显。

Objective To protect rural residents＇ health in Jilin province,make the rural drinking water security and development plan,provide scientific construction of new countryside.Methods Luyuan district was chosen to be the survey point.10 villages were selected randomly to monitor water quality,two samples each village were collected and 14 indicators were determined.Results The rate of population using non-central water supply was 97.17%,the rate of population using central water supply was 2.83%.Water quality of 10 villages was comprehensively evaluated,the results showed that water quality of 2 villages reached the first grade of standards,1 village for the second grade,1 village for the third grade and 6 villages for below the third grade.Conclusion The non-central water supply is the major pattern;the qualified rate of drinking water is low,the indictors of total hardness,total coliform group and total bacterial count obviously exceed the requirement of national standards.
