| 英文摘要 | Dissolved organic matter (DOM) plays an important role in the nutrient cycle and energy flow. However, as the key node linking anthropogenic DOM with natural ecosystems, limited attention has been paid to the fate of DOM in the municipal wastewater treatment process, especially in the combined wastewater treatment plant and constructed wetland system. In this study, the fluorescence excitation-emission matrix combined with parallel factor analysis (PARAFAC) was applied in the coupled water-processing system to elucidate the fate of DOM in the water treatment process. In terms of the relative abundance of PARAFAC components, amino acid or protein-like DOM and microbial humic-like DOM were predominantly altered in the wastewater treatment plant, whereas low-molecular-weight humic fraction and terrestrial humic-like DOM were predominantly altered in the constructed wetland. Moreover, the concentration of dissolved organic carbon was fluctuating in the system, decoupling from the removal of pollutants such as nitrogen and phosphorus. Correspondingly, the humification index, an indicator of DOM stability, mainly increased in the wastewater treatment plant, whereas the biological index and the fluorescence index exhibited greater variability in the constructed wetland. Based on the combination of the Mantel test, partial least squares path modeling, and random forest analysis, a suggestion is provided that the management of DOM stability can be coordinated with the management of nitrogen, phosphorus, and PARAFAC components like amino acid or protein-like DOM. Thus, this study provided a new picture to understand both the quality and quantity of DOM during water treatment. |
