摘要
介绍一种快速测定水和废水ＣＯＤ的分析方法．通过回收率试验和对两种不同工业废水ＣＯＤ的测试表明，该法具有简单、快速、准确和节省财力物力的优点；同时提出了该测定方法的应用对象和范围．
In this paper, an analytical method of rapidly determining water's and wasterwater's chemical oxygen demand(cod)is introduced.The analytical results of recovery ratio and chemical oxygen demand for two differrent industrial wasterwater samples, show that this method is characterized by simplicity, rapidity, and economagetion of expenses.According to the quality of water and wasterwater,the applied range of this method is proposed.
