佛山市某断面手工监测与水质自动监测对比分析

Comparative Analysis of Manual Monitoring and Automatic Water Quality Monitoring of a Section in Foshan

为研究水质自动监测与手工监测结果差异,选取佛山市某断面2020年12月到2021年11月的氨氮、高锰酸盐指数、总氮和总磷4项监测指标进行结果比对。通过研究分析监测结果之间的相对误差、相对偏差和水质类别判定,得到了采样频次、降水和社会活动等对监测结果影响较大,自动监测与手工监测结果反映到水质类别判定上,吻合度高的结论。

In order to study the difference between automatic water quality monitoring and manual monitoring, four monitoring indicators of ammonia nitrogen,permanganate index, total nitrogen and total phosphorus in a section of Foshan City from December 2020 to November 2021 were selected for comparison. Through research and analysis of the relative error, relative deviation and water quality category determination between the monitoring results, it is obtained that sampling frequency, precipitation and social activities have a greater impact on the monitoring results;automatic monitoring and manual monitoring have a high degree of agreement in the determination of water quality categories.
