COD在线监测技术综述

COD On-line Monitoring Technology:A Review

目前经济发展迅速,产生的副作用就是企业排污量巨大,而对于企业排污的监测特别是其中重要指标COD的监测就显得格外重要,而传统的监测方法:重铬酸钾消解法不能实现COD的在线监测,给了企业在监测盲区偷排的空间,而目前实现的在线监测方法各有利弊,本文分别介绍了羟基自由基(臭氧)氧化-电化学测量法、UV法、重铬酸钾-光度法几种目前主流的COD在线监测方法。

The current rapid economic development, the side effect is that enterprises have a huge amount of sewage, and ｜br the monitoring of enterprise emissions, especially the irnportant indicator of COD monitoring is particularly important, while the traditional monitoring methods： potassium dichromate digestion can not achieve COD online Monitoring, giving enterprises in the monitoring of waste management space in the blind spot, and the current online monitoring methods have their own advantages and disadvantages, this paper introduced the hydroxyl radical （ozone） oxidation - electrochemical measurement. UV, potassium dichromate-France several mainstream COD online monitoring method.
