| 摘 要： | 采用三维荧光光谱分析方法研究了某污水处理厂处理过程中的初沉池、二沉池和终沉池出水的化学耗氧量（COD）的检测方法,并对采用主成分回归（PCA）、偏最小二乘（PLS）、平行因子法（PARAFAC）及多维偏最小二乘等方法所建立校正模型的性能进行了比较,结果表明：对于工业污水COD值的检测,常规PLS要好于平行因子法及多维偏最小二乘法等三维建模方法.

| Abstract: | The three-dimensional fluorescence spectrometry was employed to analyze COD detection in the primary,secondary and final sedimentation tanks of a wastewater treatment plant;and the performance of calibration models respectively established with principal component regression （PCA）,the partial least squares （PLS）,the parallel factor analysis（PARAFAC）and the multi-way partial least squares（N-PLS） were compared to show that the conventional un-folded PLS method outperforms three-dimensional modeling methods like PARAFAC and N-PLS in COD detection. |
