| 摘 要： | 为了明确超高温堆肥新工艺在促进腐殖化进程中的优势,采用三维荧光光谱(3D-EEM)等光谱学方法研究了污泥超高温堆肥过程中DOM的结构特征及其变化规律.结果表明,堆体≥80℃的超高温阶段持续5 d(最高温度90℃),50℃以上高温阶段达到22 d,反映了堆肥过程中强烈的微生物代谢活性.E253/E203、SUVA280、S275~295等9个紫外-可见光光谱(UV-Vis)指标在0~23 d变化显著,指出DOM的芳香化和堆肥腐殖化程度逐渐增强.3D-EEM光谱结合荧光区域体积积分技术(FRI)分析指出,DOM中蛋白类物质在超高温堆肥过程的0~6 d几乎完全被降解;腐殖酸和富里酸类物质在0~23 d大量形成,堆肥在高温阶段达到完全腐熟,这与种子发芽指数(GI)在23 d所指示的腐熟度评价结果(98.5%)一致.基于多种光谱学指标的相关性分析,PⅤ,n/PⅢ,n与其它光谱学均呈现较好的相关性(r≥0.68),可以作为评价超高温堆肥腐熟度的光谱学指标.上述结果证实了超高温堆肥工艺可加快堆肥腐熟进程、缩短堆肥周期至20 d左右,在有机固废资源化领域具有极大的应用潜力.
