摘要
针对污水处理厂出水COD测量中的氯离子干扰问题,从测定原理、消除效果及适用范围等方面对常用的几种标准方法进行了比较,并对筛选出的适用方法进行了实践。结果表明,低浓度氧化剂法、氯气校正法的结果相近,是测定污水厂高浓度氯离子出水中COD的可行方法。
Concerning the disturbance of chlorine ion in determination of COD in effluent from sewage treatment plants, the conventional methods to eliminate the disturbance are compared in terms of the determination principles, the elimination effects, the application scopes and so on. The selected methods are applied in practice. The results indicate that with the similar results, the chlorine emendation method and the low-concentration oxidant method are feasible for determination of COD in effluent with high chlorine ion from sewage treatment plants.
