COD仪快速消解分光光度法测定城镇生活污水中的COD

Rapid Digestion and Spectrophotometry to Determine COD in Municipal Sewage

对COD仪快速消解分光光度法和传统重铬酸钾法作了生活污水COD测定的对比实验,并作了现场监测应用实验,结果表明,两种方法在精密度和准确度上有较好的可比性,采用COD仪快速消解分光光度法可实现对城镇生活污水COD值的快速、准确和大批量测定。

Compared two methods on determining COD in municipal sewage, the rapid digestion and speetrophotometry method and the traditional dichromate method, the results showed that both methods had good comparability in precision and accuracy, while the rapid digestion and speetrophotometry method by COD determination instrument could determine COD in a large number of municipal sewage quickly and accurately.
