摘要: This work investigates the effects of combined ozone and powered activated carbon (PAC) pretreatment on ultrafiltration (UF) performance. High performance size exclusion chromatography (HPSEC) combined with peak-fitting prediction and fluorescence excitation-emission matrix spectroscopy coupled with parallel factor analysis (EEM-PARAFAC) were used to analyze membrane fouling and organic removal. We conclude that combined ozone and PAC pretreatment can significantly inhibit an increase in transmembrane pressure (TMP) whereby ozone plays a predominant role in delaying TMP increases. Ozone and activated carbon can greatly improve the removal efficiency of organic matter, especially that of macromolecular biopolymers, medium molecules of humic-like substances and small molecular acids and neutrals; however, the removal efficiency of aromatic proteins containing tyrosine is limited. Macromolecular biopolymers show high correlations with TMP/TMP0, followed by that of building blocks of low molecular acids and neutrals, while humic-like substances have a minor influence on UF membrane fouling. Fluorescence EEM is not valid for use as an indicator of membrane fouling after combined ozone and PAC treatment according to this study.
