摘要
目前我国河湖库污染严重,化学需氧量(COD)是水质监测中表征有机物的常测项目。描述了COD的标准测定方法、快速测定法、间接测定法、在线自动监测仪的研究进展,并且指出开发具有自主知识产权、操作简单、无二次污染、性价比高的在线连续自动监测仪器是COD监测的发展趋势。
At present, rivers, lakes and reservoirs have been seriously polluted in China. The chemical oxygen demand is regularly-measured item characterizing organic matter in water quality monitoring. This paper describes the research advance about its determination method, Beginning with the standard method, it introduces improved standard method, indirect determination method, and online automatic monitoring instruments in order, And it points out that it is the development trends of COD monitor to exploit online, continuous, automatic monitoring instruments with the characteristic of autonomous intellectual secondary pollutant, the higher ratio of property to price .
