Abstract

Based on the characteristics of a COD electrochemical test method and a national standard potassium dichromate reflux method, in combination with other water quality index detection influencing COD, factor quantities are converted into specific parameter values, and the specific parameter values are combined into a whole by adopting a mathematical formula, so that the on-line COD test method and system are obtained. And carrying out intelligent dynamic correction on the whole. The COD testing system has the beneficial effects that the COD testing system is relatively high in accuracy and is suitable for performing COD online monitoring on sewage treatment plant stations, sewage pipe network key points, integrated distributed sewage treatment facilities and the like; the testing frequency of COD online testing can be greatly improved, the measuring time is short, and the efficiency is high; the consumption of toxic and harmful reagents in the process of determining the COD by adopting a reflux method is greatly reduced, and the effects of saving energy and reducing carbon are achieved.
