石亭江水质化学需氧量、高锰酸盐指数和五日生化需氧量分析

Analysis of Chemical Oxygen Demand,Permanganate Index,and Five Day Biochemical Oxygen Demand of Shiting River Water Quality

文章收集了2019年1月至2022年12月石亭江流域4个地表水点位水质中的化学需氧量、高锰酸盐指数和五日生化需氧量的监测数据,并采用Statistical Product and Service Solutions(SPSS)软件分析三个监测项目的相关性。其结果表明,石亭江流域水质中的化学需氧量与高锰酸盐指数呈显著正相关,金轮大桥点位水质中的三个监测项目之间均呈显著正相关,双江桥点位水质中的高锰酸盐指数与五日生化需氧量呈显著正相关,其余点位无显著相关关系。

This paper collected the monitoring data of chemical oxygen demand,permanganate index and five-day biochemical oxygen demand in the water quality of four surface water points in the Shiting River basin from January 2019 to December 2022,and analyzes the correlation of the three monitoring items using Statistical Product and Service Solutions(SPSS) software.The results showed that the chemical oxygen demand in the water quality of the Shiting River basin was significantly positively correlated with the permanganate index,the three monitoring items in the water quality of the Jinlun Bridge were significantly positively correlated,the permanganate index in the water quality of Shuangjiang Bridge was significantly positively correlated with the five-day biochemical oxygen demand,and the other points were not significantly correlated.
