摘要
针对工业污水处理厂出水水质COD浓度低但高氯离子的特性,探讨了高氯离子对COD测定的影响,提出了通过控制取样体积确保氯离子浓度低于2000mg/L,以低铬法进行测定的方法消除氯离子干扰,用于指导高氯废水中低COD的测定。
The effluent COD concentration in the industrial wastewater treatment plant is low but with high chloride ion. The effect of chloride ions on the determination of COD was examined. Controlling the sampling volume to en- sure the chloride ion concentration was less than 2000mg/L. Then the low chromium determination method could be adopted to eliminate the interference of chloride ion. This method could be a way to monitor the low COD in a high chlorine wastewater.
