摘　　要：针对2号活性污泥法数学模型(ASM2D)用于模拟污水处理厂工艺时,普遍存在的常规水质指标和模型水质指标转化困难且影响模型准确度的问题,基于ASM2D模型,构建进水指标与模型组分的转换路径,并通过考察污水处理厂全年的进水水质与模型水质组分情况,确定了转化系数f_TSS_(COD)(TSS对CODcr的转换因子)、f_S_A(S_(COD)与的S_(A)比值)、f_S_F(S_(COD)与的SF比值)、f_X_S(X_(COD)与的X_(S)比值)、f_X_I(X_(COD)与的X_(I)比值)以及f_S_PO(总磷与磷酸盐的比值)的取值区间。为了验证转换方法的可靠性,将实测的进水常规指标结合前述确定的转化系数,换算成模型组分指标输入模型,进行污水处理厂生化工艺的稳态和动态分析,结果表明模拟值与实测值的误差较小,模型水质转换路径可靠。When activated sludge model No.2d is used to simulate the wastewater treatment plant process,it is dif-ficult to convert conventional water quality indexes into model water quality indexes,which affects the accuracy of the model.In order to solve this problem,the transformation path of the index and water model components was built.And through the study of water quality and water quality model components for the sewage treatment plant,the value range of the conversion coefficient of f_TSS_COD(Conversion factor between TSS and CODcr),f_S_A(the ratio of S_(COD) and S_(A)),f_S_F(the ratio of S_(COD)and S_(F)),f_X_S ratio(the ratio of X_(COD)and X_(S)),f_X_I(the ratio of X_(COD)and X_(I))and f_S_PO(the ratio of total phosphorus and phosphate)were determined.To verify the reliability of the conversion method,the model component indexes were measured by conventional water inlet indexes combined with the aforemen-tioned determined conversion coefficient,and a steady and dynamic analysis of the biochemical process of the sewage treatment plant was carried out.The results showed that the error between the simulated value and the measured value was small,and the model water quality conversion path was reliable.
