Three-dimensional Excitation Emission Matrix Fluorescence Spectroscopy Combined with PARAFAC Indicating the Changes in Organic Matter in the Process of Oily Wastewater Treatment
The composition characteristics and transformation rules of dissolved organic matter in oily wastewater after biochemical treatment were studied by three-dimensional excitation emission matrix fluorescence spectroscopy and PARAFAC.The results showed that the refinery wastewater was mainly composed of tryptophan-like and tyrosine-like fluorescent components.After biochemical treatment,the aromatic content and humification degree of the effluent increased,the tyrosine-like compounds were effectively removed,and the tryptophan-like,fulvic-like and humic-like compounds were difficult to be removed.The proportion of C1 component representing tyrosine decreased sharply and the proportion of C3 component representing tryptophan increased.Among them,the C3 component could be used as an indicator to indicate the change of dissolved organic matter in wastewater.
