| 摘 要： | 本文重点讨论了在氯离子干扰下的脱硫废水COD的检测方法。在与重铬酸钾法和高锰酸钾法在氯离子干扰下不能真实的反应被测物料真实的COD值时,采用必要方法将氯离子的含量控制在干扰强度较低的浓度下开展COD检测工作。最终实现COD值的真实再现。为电石渣法脱硫系统废水指标的检测提供了新思路。

| Abstract: | The detection method of COD which is under the interference of chloride ion in desulfurization wastewater is mainly discussed in the paper. When under the interference of chloride ion, neither the potassium dichromate method nor the potassium permanganate method can detect the COD accurately. The paper presents a method which can accurately detect COD by limiting chloride ion concentration in a lower interference range. The paper presents a new method in the area of index detection in desulfuration wastewater system. |
