摘要
[目的]探讨生活饮用水浑浊度、耗氧量在各季节、不同类型水中的相关性。[方法]收集2002～2006年三门峡市区饮用水资料,对同时测定浑浊度与耗氧量的328份水样先进行两分类变量的关联性分析,再对原始数据正态性转换后采用Pearson积差相关系数进行直线相关性分析。[结果]浑浊度与耗氧量之间有较强关联性(χ2=43.21,P=0.000),各季节、类型水中除第3季度、自备水外均有较强关联性;浑浊度与耗氧量之间存在直线相关关系(r=0.401,P=0.000),除第3季度外其余各季度、类型水样相关关系均有统计学意义。[结论]以黄河为源水的生活饮用水浑浊度与耗氧量之间存在一定相关性,有机污染物是两者相关关系的内在因素。
[Objective] To explore the correlation of turbidity and oxygen consumption of drinking water in each season, different types water, [Methods] Collected data on drinking water in Smenxia City from 2002 to 2006, turbidity and oxygen consumption of 328 water samples were carried out association analysis and straight line correlation analysis. [ Results] Turbidity and oxygen consumption had the stronger association （x^2= 43.21. P=0.000）, andthey had linear correlation （r=0.401, P = 0.000）. [Conclusion] The turbidity and oxygen consumption of drinking water from Yellow River have a certain relativity, the organic pollutant is the internal factors of their related relation.
