摘　　要：采用三维荧光光谱法和传统水质分析法分别测定广州某城市污水厂污水处理过程中不同节点的污水水质,并分析荧光特性与传统分析方法获得的数据之间的关系。结果表明,随着污水水质情况的改善,污水样本的特征峰荧光强度呈现出明显的下降趋势,且污水荧光强度与COD、BOD5值存在较好的相关性,可通过直接分析污水的荧光特性来判断污水的有机污染情况;相较于过滤处理的污水样本,未过滤水样的特征峰荧光强度与污水COD、BOD5值之间具有更强的线性关系。Three-dimensional fluorescence spectroscopy and traditional water quality analysis methods were used to determine wastewater samples at different sites of WWTP in Guangzhou,in order to obtain the relationships between fluorescence characteristics and concentrations of the samples. The pollution could be estimated by analyzing the fluorescence spectra of wastewater,for understanding how the fluorescence intensity changes with the wastewater quality. The relationships between fluorescence intensity,BOD5 and COD of unfiltered samples had stronger correlation than that in filtered samples.
