| Aiming at a method of risk analysis for drinking water treatment,a statistical conceptual model was developed to simulate the pre-chlorination process in waterworks,which involved the reactions among chlorine residuals,ammonia nitrogen,bromide and organic matter.The model was calibrated and verified with field data from a typical waterworks.The model could well predict the probability distribution of the concentration of permanganate index,ammonia nitrogen,chloroform,bromodichloromethane,chlorodibromomethane and bromoform in the prechlorination process. |
