摘　　要：应用数学模拟技术需要了解污水的水质特性,只有具备详细的污水水质特性参数才能更准确地模拟、预测污水处理工艺的运行效果。采用TUD联合模型需将COD区分为SA、SF、SI、XS和XI等5种组分。对这5种组分的测定方法进行了探索,其中SA可采用五点pH值滴定法(5P-VFA)确定,采用BOD-t曲线法可确定缓慢可生物降解有机物(XS)。最后测得北京某污水处理厂进水COD的5种组分的质量分数分别为:SA=6.49%,SF=36.23%,SI=13.04%,XS=32.62%,XI=11.62%。It is necessary to define wastewater characteristics in application of mathematical simulation technology. The detailed wastewater characteristics will result in accurate simulation results. TUD model needs to have five COD components： SA, SF, SI, XS and XI. The method to determine the five components was discussed. SA is determined by 5-point pH titration method, and slowly degradable COD （Xs） is determined by the curve of BOD-t. The mass fractions of five COD components in the influent of a wastewater treatment plant in Beijing are as follows： SA =6.49%, SF =36.23% , SI =13.04% , Xs =32.62% and XI = 11.62%.
