洱海水中化学需氧量、高锰酸盐指数和五日生化需氧量的相关性分析

Correlation Analysis of Chemical Oxygen Demand,Permanganate Index and Five-Day Biochemical Oxygen Demand in Erhai Water

本文结合2018年1月至2020年12月洱海水中化学需氧量、高锰酸盐指数和五日生化需氧量的月均值数据,分析三个监测项目的相关性。研究表明,基本可以利用单一指标来预测或估算其他两项指标的范围,这对于监测数据预判和数据合理性审核具有一定的指导意义。

Combining the monthly average data of chemical oxygen demand,permanganate index and five-day biochemical oxygen demand in Erhai water from January 2018 to December 2020,this paper analyzes the correlation of the three monitoring items.Research shows that a single indicator can basically be used to predict or estimate the scope of the other two indicators,which has certain guiding significance for monitoring data prediction and data rationality review.
