Abstract

Road runoff underwent treatment using a filter filled with sludge from drinking water treatment plants to assess its capacity for removing dissolved organic matter (DOM). This evaluation utilized resin fractionation, gel permeation chromatography, three-dimensional excitation-emission matrix fluorescence spectroscopy, and UV-Visible spectroscopy. The filter demonstrated enhanced efficiency in removing dissolved organic carbon, achieving removal rates between 70 and 80%. It effectively targeted macromolecular DOM components present in road runoff, with hydrophobic organic compounds showing higher removal rates than hydrophilic ones. Additionally, acidic and neutral organic substances were preferentially removed over basic organic compounds. Fluorescent substances identified in road runoff DOM included fulvic acid-like, humic acids, and protein-like substances, all of which exhibited significantly reduced intensities in fluorescence peaks after filtration. Furthermore, filtration led to a decrease in the aromatization and humification of runoff DOM due to the effective removal of aromatic compounds and macromolecular structural components.

使用装有饮用水处理厂污泥的过滤器对路面径流进行处理，以评估其去除溶解有机物（DOM）的能力。这项评估采用了树脂分馏、凝胶渗透色谱法、三维激发-发射矩阵荧光光谱法和紫外-可见光谱法。该过滤器在去除溶解有机碳方面表现出更高的效率，去除率在 70% 到 80% 之间。它能有效针对道路径流中的大分子 DOM 成分，疏水性有机化合物的去除率高于亲水性有机化合物。此外，酸性和中性有机物的去除率高于碱性有机物。在道路径流 DOM 中发现的荧光物质包括类富勒烯酸、腐殖酸和类蛋白物质，所有这些物质在过滤后的荧光峰强度都明显降低。此外，由于有效去除了芳香族化合物和大分子结构成分，过滤还降低了径流 DOM 的芳香化和腐殖化程度。
