摘要
本文的研究目的为通过对菌落总数、溶解性总固体以及总硬度指标特征的分析,探讨三个指标之间的关系。采用的研究方法为收集2009年度年鄂尔多斯市饮用水水质监测数据,分析饮用水菌落总数、溶解性总固体以及总硬度的影响因素,用相关性分析来研究三者之间的关系。研究结果表明,通过对菌落总数与溶解性总固体进行单相关分析,相关系数为0.134(0.1<P<0.3),说明两者存在着一定联系。对菌落总数与总硬度进行单相关分析,相关系数为0.079(P<0.1),说明两者相关性不大。与此同时对溶解性总固体和总硬度也进行了单相关分析,相关系数为0.546(0.5<P<1),说明两者具有明显相关性。
The purpose of this study is through the index and characteristic analysis of total plate count, total dissolved solids and total hardness, to explore the relationship between the three indicators. Research method of this article is by collectting Erdos monitoring data of drinking water in 2009, to analyz factors of total plate count, total dissolved solids and total hardness and use the methed of relative analysis to study the relationship between them.The result show that through the analysis of total plate count and total dissolved solids, the correlation coefficient was 0.134(0.1 <P <0.3),which shows there is some link between them.Total plate count and total hardness shows little correlation through the analysis of them, because the correlation coefficient was 0.079(P <0.1).At the same time,through the analysis of total dissolved solids and total hardness, the correlation coefficient was 0.134(0.1 <P <0.3),which shows a clear correlation between them.
