化学需氧量和高锰酸盐指数相关性探讨研究

选取淮河流域临沂市4个出境监测断面2014年1～11月，每月上下旬各一次化学需氧量和高锰酸盐指数浓度的分析，利用每个监测断面21对化学需氧量和高锰酸盐指数浓度的监测结果，分析了临沂境内4个出境断面两个水质参数的相关关系，给出各断面二者的一元线性回归方程及相关系数并 F检验，得出不同断面二者的相关性及因水质不同相关性的差异。通过分析同一样品的二者的监测结果的相关性，相互佐证，从多角度进行质量控制和质量保证。提出二者相关性分析结果在实际使用的建议，以期引起从事水环境监测分析、监测评价和监测管理等相关人员重视。

Correlation Research between COD and Permanganate Index for Linyi Section of Huaihe River

This study selects for data from four exiting monitoring sections of Huaihe River in Linyi from January to November 2014, analyze chemical oxygen demand(COD)and permanganate index concentration of them twice on a month.It uses 21 pairs COD and the concentration of potassium permanganate index of each monitoring section to analyze the correlation between the 4 mo-nitoring section and the 2 water quality parameters, and give them unary linear regression equation and correlation coefficient of each monitoring section and F test, and get the two correlation and difference because of different water quality of each monitoring sec-tion.Through the analysis of the monitoring results of both of the same sample correlation and mutual support , quality control and quality assurance were done from various aspects.In order to attract public attentions for this field, this paper pointed out the practi-cal values of correlations studies.
