Abstract

Abstract The aim of the study was to assess the transformation of humic substances during composting of biomass of energetic plants and municipal solid waste. The type of the organic material to be composted and the type of technology used affect the course of the humic substances transformation and formation of compost maturity parameters. Compost produced from the mixture of energetic willow and hay biomass contained humic substances with higher share of low-molecular fractions and lower share of humic acids in total organic carbon than those produced from municipal solid wastes. Obtained results also showed that insoluble alkali fraction plays an important role in humification process by its convertion to a new humic substances. Share of humic and fulvic fractions in relation to the total organic carbon appears to be reliable indicator of composting as a process of enhancing organic matter humification.

从城市固体废物和高能植物生物量中产生的不同成熟度的堆肥腐殖质物质
摘要本研究旨在探讨高能植物生物质和城市生活垃圾堆肥过程中腐殖质物质的转化。堆肥有机物的种类和堆肥工艺影响腐殖质转化过程和堆肥成熟度参数的形成。与城市固体废弃物相比,含能柳与干草混合堆肥所含腐植酸在总有机碳中所占的比例更高,腐植酸所占的比例更低。结果还表明,不溶性碱组分在腐殖化过程中转化为一种新的腐殖物质,发挥了重要作用。腐殖质和腐殖质组分相对于总有机碳的份额似乎是堆肥作为一个增强有机质腐殖化过程的可靠指标。
