| 摘 要： | 利用城市生活垃圾进行堆肥，对堆肥前后水溶性有机物的荧光光谱进行分析。结果表明，水溶性有机物发射光谱相对简单，堆肥前在400 nm附近分别形成一个较强的荧光强度峰，而激发光谱与同步扫描光谱则由几个特征峰及肩峰组成。堆肥结束后，水溶性有机物在440 nm新形成一个较强的荧光强度峰；荧光激发与同步扫描光谱主峰的位置也发生明显的改变。对水溶性有机物发射、激发及同步扫描光谱的特征峰进行分析证实，堆肥结束后，水溶性有机物中含有较高的分子缩合度与芳构化程度，并与富里酸类物质相似，表明堆肥产品施入土壤后活性较高。

| Abstract: | Municipal solid waste(MSW) composting was conducted,and the fluorescence spectral characteristic of dissolved organic matter(DOM) during MSW composting was determined.At initial stage of MSW composting,emission spectroscopy of DOM was relative simple,and exhibited a peak at 400 nm;while exhibited several peaks and shoulder peaks.At final stage of MSW composting,DOM emission spectroscopy exhibited a new peak at 440 nm,and the wavelength of main peaks of excitation and synchronous spectroscopy were changed.An... |
