中文摘要：

为了筛选生活垃圾堆肥过程中最佳的复合菌剂接种方式,试验对堆肥起始接种、高温期接种、高温后接种、后腐熟接种和不接种菌剂五种不同接种方式下的生活垃圾堆肥过程中水溶性有机物（DOM）进行光谱分析,考察了生活垃圾堆肥中DOM组成随堆肥时间的变化规律。DOM荧光光谱解析表明：随着堆肥时间的增加,五个不同处理堆体中的DOM光谱学特性呈现出一定规律的变化趋势,结构复杂的大分子物质和腐殖质类物质不断增多,DOM性质逐渐趋于稳定化。从DOM的荧光图谱及相关参数综合比较而言,堆肥起始和越过高温期的高温后接种微生物复合菌剂,能够明显地加速堆肥的腐殖化进程。

英文摘要：

In order to determine the best inoculation methods of compound microorganisms in solid waste composting,dissolved organic matter（DOM） during the process of composting under five different inoculation methods,including inoculation at the start,at the high-temperature phase,after the high-temperature phase,at the maturity phase and without inoculation,was tested through spectral analysis to investigate the time variations of DOM components in solid waste composting.Fluorescence spectra analysis of DOM indicated that the spectral characteristics of DOM in the composting piles of the five treatments exhibited a certain trend with composting time increasing,in which macromolecules with complex structures and humic substances gradually increased,and the heap materials became more and more stabilized.According to the comparisons of the fluorescence spectroscopy maps and related parameters,the treatment of inoculating compound microorganisms at the start time or after the high-temperature phase could notably speed up the humification process in solid waste composting.
