本研究对比分析了传统生态混凝土（TEC）护岸处理和新型改良多骨料生态混凝土（IMAEC）护岸处理对雨水道路径流的水质净化效果，以及溶解有机质（DOM）结构和组成的变化。结果表明，TEC处理对化学需氧量（COD）、总氮（TN）和总磷（TP）的去除率分别为14.56% ~ 30.49%、38.21% ~ 67.96%和24.22% ~ 41.14%，IMAEC处理对化学需氧量（COD）、总氮（TN）和总磷（TP）的去除率分别为51.22% ~ 57.90%、64.61% ~ 81.95%和40.29% ~ 53.45%，表明IMAEC护岸处理比TEC护岸处理具有更高的净水性能。SUVA254、a250/a365和a253/a203的结果表明，IMAEC处理对难降解芳香族化合物具有较高的去除率。平行因子（PARAFAC）分析表明，TEC处理对腐殖质样组分1、2和蛋白样组分3的去除率分别为27.94%、9.69%和27.86%，IMAEC处理对3种荧光组分的去除率分别为51.35%、30.10%和52.97%。2D-COS图谱显示，类蛋白质物质比类腐殖质物质更容易受到金属离子的影响。类蛋白材料可以优先与金属离子相互作用，从而有效去除dom -金属配合物，并进一步影响金属离子的迁移和转化。
This study comparatively analyzed the performance of water quality purification on stormwater road runoff, and the changes in the structure and composition of dissolved organic matter (DOM), after traditional ecological concrete (TEC) revetment treatment and a new improved multi-aggregate ecological concrete (IMAEC) revetment treatment. The results showed that the removal rates for chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) reached 14.56%–30.49%, 38.21%–67.96%, and 24.22%–41.14% respectively, in the TEC treatment, and 51.22%–57.90%, 64.61%–81.95%, and 40.29%–53.45% respectively, in the IMAEC treatment, suggesting that the IMAEC revetment treatment showed higher water purification performance than the TEC revetment treatment. The results of SUVA254,a250/a365 anda253/a203 indicated that the IMAEC treatment showed relatively high removal efficiencies of refractory aromatic compounds. Parallel factor (PARAFAC) analysis indicated that the removal rates for three fluorescent components (humic-like Components 1 and 2, and protein-like Component 3) reached 27.94%, 9.69% and 27.86 respectively, in the TEC treatment, and 51.35%, 30.10%, and 52.97% respectively, in the IMAEC treatment. 2D-COS mapping suggested that protein-like materials were more susceptible than humic-like substances, to the addition of metal ions. Protein-like materials can preferentially interact with metal ions, resulting in the effective removal of DOM-metal complexes, and can further influence the migration and transformation of metal ions.
