Abstract:Dissolved organic matter (DOM) in a biological effluent collected from a typical petrochemical wastewater treatment plant was isolated and fractionated using resin adsorption method. The fractions were operationally categorized as hydrophilic substances (HIS), hydrophobic acids (HOA), hydrophobic neutrals (HON), and hydrophobic bases (HOB). The dissolved organic carbon (DOC), specific UV absorbance, three dimensional excitation emission matrix fluorescence spectroscopy (3DEEM), ultraviolet spectrum and infra-red spectrum characteristics of the 4 fractions were analyzed. HIS and HOA were the main fractions and they occupied 49% and 29% of DOC in the effluent, respectively. The fraction of HON contained more aromatic proteins and soluble microbial products, while the fraction of HIS contained more humus, which were predominately microbial products derived by the analysis of 3DEEM. The peaks of infra-red spectrum of the 4 fractions mainly distributed in the district of 600~1200cm-1, indicating that similar compounds of balmy isomers exist in the wastewater samples.
