相关性分析在饮用水水质卫生检验和控制中的应用

Application of Correlation Analysis in Drinking Water Sanitary Examination and Quality Control

摘要:
目的利用溶解性总固体与总硬度、氯化物和硫酸盐之间的相关性，验证水样测定数据的有效性和可靠性。
方法根据《生活饮用水标准检验方法》（GB/T 5750-2006）进行检验。
结果溶解性总固体与总硬度、氯化物和硫酸盐之间的相关性有非常显著意义。
结论采用分析水样不同特性结果的相关性作为质量控制方法，对检验结果的准确性、合理性和有效性起到指导和评价作用。

Abstract:
Objective To study the correlations of total dissolved solids with total hardness, chloride and sulphate to verify the validity and reliability of data in the sanitary examination of drinking-water quality.Method The examination methods were based on the Standard Examination
Methods for Drinking Water (GB/T 5750-2006).
Result There were some strong correlations of total dissolved solids with total hardness, chloride and sulphate.
Conclusion The correlations of total dissolved solids with total hardness, chloride and sulphate in different water samples could be used as a method for the quality control of data, which has played an effective role in the appraisal of accuracy, rationality and validity of results.
