地表水中总磷、氨氮、化学需氧量的相关性研究

Study on the Correlation of TP,NH3-N and COD in Surface Water

分析了2019年度黄石市地表水7个断面(点位)不同时期的总磷、氨氮和化学需氧量的监测数据。结果表明:在枯水期、平水期和丰水期,总磷与氨氮、化学需氧量浓度值具有相关性,丰水期相关系数大于枯水期和平水期。为此,提出了在日常的工作中,监测人员可以根据总磷、氨氮和化学需氧量中某一参数的测定,确定另外两个参数的大致浓度范围,预估稀释倍数,以提高监测效率。

This paper analyzes the monitoring data of TP,NH 3-N and COD of 7 sections(points)of surface water in Huangshi City in different periods in 2019.The results shows that in the low water period,the normal water period and the high water period,the TP is correlated with the concentration of NH 3-N and COD,and the correlation coefficient in the high water period is higher than that in the low water period and the normal water period.Therefore,in daily work,the monitoring personnel can determine the approximate concentration range of the other two parameters according to the determination of a certain parameter in TP,NH 3-N and COD.The dilution ratio can be estimated to improve the monitoring efficiency.
