| 摘 要： | 天津引滦1号监测点位于饮用水水源地于桥水库上游,负责对入境饮用水水质实施监测。通过对1号点位2012年-2013年TOC和CODMn相关关系的分析研究,得出该时期TOC和CODMn之间显著线性相关,一元线性回归方程为CODMn=0.62 TOC+1.15。这也说明2012年-2013年天津引滦水源水质基本稳定。对TOC与CODMn相关关系的研究,可以为水源地TOC在线监测逐步代替CODMn监测提供实践依据。

| Abstract: | No. 1 monitoring substation in Tianjin was located at the upstream of drinking water source Yuqiao Reservoir. It is responsible for monitoring of the drinking water quality. Analysis and research of the relationship between TOC and CODMn in 2012 -2013 proved significant linear correlation between TOC and CODMn during this period. Simple linear regression equation was CODMn = 0. 62TOC ＋ 1.15. The quality of drinking water sources of Tianjin was basically stable. Study on the relationship between TOC and CODMn provided practice basis for the gradual replacement of CODMn with TOC monitoring. |
