Abstract

ABSTRACT The most frequent way to survey green waste composts is to monitor the temperature during the composting process. However, if the temperature is a good index for global biological processes, it is not for the chemical stability. In order to identify a reliable index, this work investigates water extraction coupled to spectroscopic indexes such as E2/E3, E4/E6, and SUVA254 ratios, and fluorescence indexes such as Kalbitz, Milori, CP/PARAFAC, and Fluorescence Region Integration. The measurements of these indexes are carried out with six samples from different sites with different green waste material composition. The results show that most indexes depend on the green waste origin more than the composting time; some depend mostly on the material origin while others on compost age. A comparison of these results indicates that the biochemical process occurs more rapidly than expected by the compost producers. The combination of these indicators gives useful information on the processes that take place during composting.

紫外线-可见光和荧光绿色废物堆肥监测:材料依赖性
摘要调查绿色垃圾堆肥最常见的方法是监测堆肥过程中的温度。然而,如果温度是全球生物过程的一个好指标,那么它就不是化学稳定性的指标。为了确定可靠的指标,本工作研究了水提取与光谱指标(如E2/E3、E4/E6和SUVA254比率)以及荧光指标(如Kalbitz、Milori、CP/PARAFAC和荧光区积分)的耦合。这些指标的测量是用来自不同地点的六个具有不同绿色废物成分的样品进行的。结果表明,大多数指标更多地取决于绿色垃圾的来源,而不是堆肥时间;有些主要取决于材料来源,而另一些则取决于堆肥年龄。这些结果的比较表明,生化过程的发生速度比堆肥生产商预期的要快。这些指标的结合为堆肥过程提供了有用的信息。
