Effects of DOM characteristics from real wastewater on the degradation of pharmaceutically active compounds by the UV/H2O2 process
文献摘要：
The characteristics of dissolved organic matter(DOM)can significantly affect the degrada-tion of target compounds by the advanced oxidation processes.In this study,the effects of the different hydrophobicity/hydrophilicity fractions,molecular weight(MW)fractions,fluorescence components and molecular components of DOM extracted from municipal wastewater on the degradation of 4 pharmaceutically active compounds(PhACs),includ-ing carbamazepine,clofibric acid,atenolol and erythromycin by the UV/H202 process were investigated.The results showed that the degradation rate constants of 4 PhACs decreased dramatically in the presence of DOM.The linear regressions of 4 PhACs degradation as a function of specific fluorescence intensity(SFI)are exhibited during the degradation of 4 PhACs and the SFI may be used to evaluate effect of DOM on target compounds in wastewa-ter.The hydrophobic acid(HPO-A)exhibited the strongest inhibitory effect on degradation of 4 PhACs during oxidation process.The small MW fractions of DOM significantly inhibited the degradation of 4 PhACs during oxidation process.Among three fluorescence components,hydrophobic humic-like substances may significantly inhibit the degradation of 4 PhACs during oxidation process.At the molecular level,the formulas may be derived from terres-trial sources.CHO compound may significantly inhibit the degradation of 4 PhACs during oxidation process on formula classes.The unsaturated hydrocarbons,carbohydrates and tannins compounds may significantly inhibit the effectiveness of the UV/H202 process on compound classes.
