摘要
针对某污水处理厂出水COD测量中的氯离子干扰问题,建立了一种新的COD测定方法。结果表明,该方法能消除氯离子对COD测定的干扰,具有较高的准确性和稳定性,且设备简单、操作简便、成本低,适合污水厂高浓度氯离子出水中COD的检测。
Aimed at the interference of chloride ion on COD determination in effluent of sewage treatment plant, a new method of COD determination was established. The results showed that it could eliminate interference of chloride ion on COD determination. This method had high accuracy and stability, simple equipment, convenience operation and lower cost. It was suitable for COD determination in effluent with higher concentration of chloride ion.
