地表水感潮断面COD_(Mn)分析方法研究

Study on CODMnanalysis methods of surface water tidal section

COD_(Mn)是地表水环境监测的必测项目,为确保监测数据准确,对感潮断面COD_(Mn)分析方法的合理选择进行研究.通过对地表水感潮断面COD_(Mn)分析方法的研究,综述了感潮断面COD_(Mn)的研究现状,并提出了以盐度0.5作为感潮断面COD_(Mn)分析方法选择的依据.

COD_（Mn）is an essential item tested in monitoring the surface water environment.In order to ensure the accuracy of the monitoring data,some researches have been done in the reasonableselection of the COD_（Mn）analysis methods in monitoring Tidal Section.Based on the study of COD_（Mn） analysis methods of surface water tidal section,this paper summarizes the research status of COD_（Mn）in tidal section,and puts forward that salinity 0.5 can be used as the basis for the selection of COD_（Mn） analysis methods in monitoring tidal section.
