| 摘 要： | 针对重铬酸钾回流法测定COD消解时间长，分析费用高等不足，研究了COD消解装置在测定印染废水CODcr中的应用，通过对消解时间和催化剂用量的选择，确定了COE消解装置测定絮凝处理前后印染废水CODcr的最佳条件，并且测定结果与回流法一致，该方法具有操作简便，分析费用低，消解时间短及精密度好等特点。

| Abstract: | Because classical method had deficiencies of long digestion time and expensive analysis cost,COD digestion instrument was developed for determination of COD Cr of dyeing wastewater.The optinum conditions were established by testing digestion time and amount of catalyst.The results were identified with those of the classical method.It implies that this method has the advantages of rapid digestion,high accuracy,low cost and simple operation,and will have extensive applications. |
