Safety Investigation and Water Quality Analysis of Cellar Water in Southeast Gansu

对陇东南地区窖储水通过检测总硬度、Fe、Cu、Pb、Zn、溶解性总固体、生化需氧量(COD)、大肠杆菌和pH值等作了较为全面的水质分析,并参照国家饮用水标准作了比较。结果表明,一些指标严重超标。最后通过实地调查和对测定结果的综合分析,提出了保证饮水安全的合理建议。

The cellar water in southeastern Gansu was made an overall analysis through detecting the general hardness,the content of Fe,Cu,Pb and Zn,the dissoluble general solid,COD,the content of Escherichia Coli and pH,and the comparison of the test results with national drinking water standard was made.The result shows that some indexes are exceeding standard greatly.Moreover,some reasonable suggestions of guarantee drinking safety were proposed by field survey and analysis of detecting results at last.
