摘要：The pollution of natural waters has considerably increased in the last decades. This causes an increase of the organic and inorganic pollutant concentrations in water. The chlorination of the surface waters for disinfection purpose can resulted in the production of organohalogen co mpounds, and mostly trihalomethanes (THMs), which present toxicological risks. The aim of this study is to stud y the chlorination break point and to measure disinfection by-products production following uses of different processes for treatment of water polluted b y natural or anthropogenic organic matter, which could be present in surface water. After characterization, surface water samples have been polluted with 500 μg/L of different organic compounds, which are more or less oxidable precursors (resorcinol > acetone > phenol). Results sho wed that chlorination break point and SPD production vary with the type of the pollutant and the configuration of the water treatment process. Finally, this study has clearly demonstrated that the use of a coagulation step before the chlorination step allows a decrease of the SPD production
