Evaluation of DBPs Formation Potential during Chlorination of Dissolved Organic Matter Fractions Isolated from Eutrophic Water

摘要：

Dissolved organic matter (DOM) in water from eutrophic water source was isolated into four classes as hydrophilic substances (HIS), hydrophobic acids (HOA), hydrophobic neutrals (HON), and hydrophobic bases (HOB). The formation of Trihalomethanes (THMs) and Haloacetic acids (HAAs) in chlorination of different DOM fractions was evaluated. The dominate species of THMs and HAAs were chloroform (CF) and trichloroacetic acid (TCAA) in the chlorination of raw water. There were close linear relationship between THMs/HAAs yields and SUVA254 values. Increasing of contact time and chlorine dosage enhanced the formation of THMs/HAAs yields from different DOM fractions. The increase of pH leads to more formation of THMs, and the highest production of HAAs was observed at pH 7.
