目的了解德惠市部分农村生活饮用水水质状况,切实做好2010—2013年农村饮水安全工程规划编制工作。方法采用分层随机抽样法从全市308个行政村中选取91个行政村44户农户为检测户,进行水质监测和评价。结果 44份水样均来自农户分散式供水系统,均为浅井水,水质合格率为13.6%。所检指标合格率:浑浊度和肉眼可见物47.7%,硝酸盐氮84.1%,总硬度90.9%,氨氮97.7%,铁47.7%,锰45.5%,总大肠菌群38.6%,耐热大肠菌群64.7%;色度、嗅和味、pH值、氯化物、耗氧量、溶解性总固体、氟化物、砷、硫酸盐和菌落总数均为100%。结论德惠市农村饮用水水质较差,极需改善。
Objective To understand the quality of drinking water in some rural areas of Dehui City and to effectively plan the preparation of rural drinking water safety projects in 2010-2013. Methods A stratified random sampling method was used to select 44 households in 91 administrative villages from 308 administrative villages in the city as test users for water quality monitoring and evaluation. Results All the 44 water samples from the farmer’s decentralized water supply system were as shallow well water with a pass rate of 13.6%. The passing rate of the seized indicators: turbidity and macroscopic 47.7%, nitrate nitrogen 84.1%, total hardness 90.9%, ammonia nitrogen 97.7%, iron 47.7%, manganese 45.5%, total coliform 38.6%, heat-resistant coliform 64.7%; total color, smell and taste, pH, chloride, oxygen consumption, total dissolved solids, fluoride, arsenic, sulphate and colony are all 100%. Conclusion Dehui rural drinking water quality is poor, it is necessary to improve.
