摘要
结合PARAFAC模型研究了污水处理厂进出水的三维荧光光谱特征。结果表明城市生活污水具有4个荧光区域,其中 进水的1区和2区荧光中心较为明显,3区和4区荧光中心不明显;出水的四个荧光区都较为明显。运用平行因子法 分析得出进水和出水DOM均含有3种主要的荧光组分,分别是类色氨酸、类酪氨酸和类腐殖质。3种荧光组分的得 分值可以作为城市生活污水的另一荧光特征,根据得分值可以判断出进水中最不稳定的是类色氨酸和类酪氨酸,类腐 殖酸则相对较为稳定。
Abstract
Three dimensional excitation-emission fluorescence spectra characteristics of influent and effluent from urban domestic sewage treatment plant were analyzed combined with PARAFAC model. The results indicated that urban sewage has four fluorescence centers. The 1 and 2 fluorescent center of influent were obvious. However, 3 and 4 fluorescence centers were blurry. All the four fluorescence centers of effluent were quite obvious. Combining PARAFAC model, both the influent and effluent contain three kinds of fluorescence compositions, which are tryptophan-like、 tyrosine-like and fulvic-like. The scoring values of three kinds of fluorescent compositions can be used as another fluorescence feature of urban sewage. According to the scoring values, tryptophan-like and tyrosine-like are unstable in both influent and effluent, but fulvic-like is relatively stable.
