Pig Manure and Straw Ferment Produce Heat Collaboratively and Transformation of Dissolved Organic Matter

  • 摘要: 采用量热计法和三维荧光光谱,分别对猪粪发酵产热不同阶段温度、热值以及溶解性有机质(DOM)的转化特征进行了研究. 结果表明:在不同C/N(猪糞与芦苇秸秆物料配比)的4组发酵产热试验中,纯猪粪发酵产热温度高于室温时间达到60d,累积热量损失最多达8.862kJ/g,是增温技术最为理想的配比;随着发酵产热的进行,纯猪粪发酵产热样品中类蛋白化合物荧光比值(P1,n+P2,n,0.625~0.546)逐渐减少,类富里酸物质荧光比值(P3,n,0.140~0.173)与类胡敏酸物质荧光比值(P5,n,0.051~0.097)逐渐增多,腐殖化程度逐渐加强,但是与其他各组相比其腐殖酸类物质增加最少,腐殖化程度最低;不同C/N物料产热过程中,尽管不同区域的荧光强度与热值的相关性不同,但不同C/N物料释放的热量均来源于微生物对简单有机化合物的分解.
