摘要：

The main purpose of this study is to look into the fate of dissolve organics through conventional water treatment processes preceded by prechlorination with high dosage to treat polluted raw water. In addition to organic surrogate parameters analyses, organics were fractionated into humic acid, fulvic acid, hydrophilic-acid and -neutral-four fractions. The results showed that the removal of hydrophilic fraction organics were limited, and prechlorination probably transformed some organics from other fractions into hydrophilic-neutral fractions.Therefore although prechlorination with high dosage could facilitate the plant operation when treating polluted raw water, it probably had some adverse effect on dissolved organics removal.
