【摘要】 为发现并解决N市部分地区农村饮用水水源水质的问题,开展N市农村饮用水水质安全评价研究。结果是感官指标的色度、浑浊度、异臭和异味、肉眼可见物分别超过生活饮用水卫生标准的水质常规限值比例为22%、59%、6%和16%;微生物指标的大肠杆菌、总菌落数和耐热大肠杆菌含量分别超出标准的比例为19%、12%和4%;化学指标pH值、铁、锰含量超标的占18%、56%、49%;毒理学指标氟化物含量超标的占7%,砷含量严重超标的约占53%。农村饮用水水质不安全内因是由于地质构造与水文地质条件所致,外因是直接供水。建议增加农村饮用水水处理设施、消毒设施和水质检测设备,保证农村饮用水真正安全。更多还原

【Abstract】 Althouth many new wells use the rural drinking water since China start the rural drinking water safety project,it has many limitations and problems.The purpose of this paper is to explain the well for rural person in N City in Heilongjiang Province of China drinking water whether or not meet for rural drinking water quality standard and.in particular,what it relates to the water quality index.The result reveal that water quality index include turbidity,coliforms.total bacterial.PH.errum(Fe) and manganese(Mn) exceeded the drinking water quality healthy standard GB 5749—2006 normal regulations limit value percentage is 59%.19%.12%.18%.56%and 49%of samples;respectively,toxicology such as fluoride(F) were found in 7%above the provisional guideline value,and arsenic(As) were found in 53%above.As no clear relationship was found,we conclude water quality unsafe because of geological structure and hydrogeological conditions and direct drinking deep well water.Suggestions to increase the rural drinking water treatment facilities,disinfection facilities and water quality inspection equipment,make sure the rural drinking water safety and healthy.更多还原
