摘要：

To improve water quality, a pilot-scale evaluation into upgrading the conventional treatment process was conducted. By following DOC content, UV254 absorbance, SUVA and by-products formation, three oxidative pre-treatments were evaluated: pre-ozonation (2.2 g O-3/m(3)); O-3/H2O2 process (2.2 g O-3/m(3); H2O2: O-3 = 1: 2) and O-3/ H2O2 process (2.2 g O-3/m(3); H2O2: O-3 = 2: 1). The second pre-treatment gave the best results, with a final average DOC content of 0.9 mg C/L, UV254 absorbance of 0.06 cm(-1) and the lowest THMFP of 130 mu g/L. UV254 absorbance can serve as a proper indicator for predicting THM and HAA formation, yielding a correlation coefficient >= 0.90.
