摘要
在污水厂高氯出水水样COD的测定过程中,氯化物是主要干扰物质,如何选取最好的测定方法而避免和消除其干扰是测定的关键。为此,通过对天津泰达威立雅水务有限公司污水处理厂出水水质的分析,将出水水样分为可滤和不可滤两部分,分别用国标法和标准曲线校正法进行COD的测定,其和就是出水水样COD的最终结果。大量试验证明,此方法测定结果准确、可靠。
During the determination of COD in high chlorine effluent of WWTP, chloride is the main interference material. How to select the best method to avoid and eliminate the interference is the key of the determination. To this end, through the effluent quality analysis of Tianjin Taida Veolia Water Co. Ltd. , the effluent is divided into two parts, filterable and non-filterable, and the national standard and the standard calibration curve method are used for the determination of COD respectively. Their sum is the final result of effluent COD. A large number of tests prove that this method has accurate and reliable result.
