Abstract：The characteristics of DOM in secondary effluent at different ozone dosages were investigated based on EEM parallel factor analysis. There were three fluorescent components in secondary effluent. Component 1was protein-like substances and the other two components were humic-like substances. The three components will react with ozone intensively at ozone dosage 0.98mgO3/mgTOC. Linear regression analysis showed that the reaction between ozone and component 1and 2could account for the removal of color, UV254and UV280. In addition, the HPLC-SEC analysis confirmed the PARAFAC analysis results and revealed that ozone will react preferentially with small molecular weight substances in component 1. However, there was little reaction between ozone and high molecular weight substances in component 1.
