摘　　要：污水水质特征化是模拟污水处理工艺运行系统的1个重要步骤。只有了解污水水质特性,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。研究采用的活性污泥模型将污水中有机物COD区分为溶解性易挥发性有机酸SA、溶解性可发酵易生物降解有机物SF、溶解性不可降解(或惰性)有机物SI、颗粒性缓慢可生物降解有机物XS和难溶性不可降解有机物XI这5种成分。研究采用五点pH值滴定法(5P-VFA)确定SA,采用BOD-t曲线法可确定XS。测得内蒙古某污水处理厂进水COD组分的质量分数分别为:SA=4.85%,SF=33.93%,SI=14.24%,XS=32.95%,XI=14.03%。Wastewater characterization for COD is the key procedure in modeling application.It＇s necessary to define wastewater characteristics in application of mathematical simulation technology.The detailed wastewater characteristics will make accurate simulation results.Activated sludge model adopted here needs to have five COD components： SA,SF,SI,XS and XI.SA is determined by 5-point pH titration method,and slowly degradable COD（XS） is determined by the imitated curve of BODt-t.The mass fractions of five COD components in the influent of a wastewater treatment plant in Inner Mongolia are as follows： SA= 4.85%,SF = 33.93%,SI = 14.24%,XS = 32.95% and XI = 14.03%.
