N2 - The kinetics and mechanisms of chlorine dioxide and chlorine in water distribution network is described, and a multi-species network water quality model is built in this paper. Experiment was composed of two parts, static test and dynamic test. The cast iron pipe, steel pipe, and PVC pipe were selected to carry out static experiments. In order to study the kinetic and mechanism of the combination disinfection of chlorine dioxide and chlorine, the reaction was under the condition of different chlorine dioxide and chlorine dosing ratio and different chlorination method. Dynamic experiments carried out in the cast iron pipe in different chlorine dioxide and chlorine dosing ratio and different flow conditions to study the kinetic and mechanism of the combination disinfection of chlorine dioxide and chlorine.A multi-species network water quality model using EPANET-MSX toolkit is built based on kinetic and mechanism of the combination disinfection of chlorine dioxide and chlorine. The concentration of residual chlorine (Cl2), chlorine dioxide (ClO2), chlorite in the bulk water and biofilm was taken as the main parameters. And the model was calibrated by the experiment data. The water quality model application in a large water distribution network, of which the total demand is 800,000 m 3/d in China. The results show that the combination of chlorine dioxide and chlorine disinfection can reduce the chlorine and chlorine dioxide disinfection by-product and residual chlorine concentration distribution was more reasonable.
