%X Aiming at a method of risk analysis for drinking water treatment, a statistical conceptual model was developed to simulate the chlorination disinfection processes in a conventional waterworks. The model involved the chemical reactions among organic matter, chlorine residuals, ammonia nitrogen and bromide as well as the physical and biological mechanisms in the coagulation-flocculation, sedimentation and post-chlorination processes. Field data from a typical waterworks demonstrated that the model could well predict the probability distribution of the concentration of permanganate index, ammonia nitrogen and four kinds of trihalomethanes (THMs). A Monte Carlo simulation showed that the violation probability of permanganate index and each THM of the effluent of the waterworks is extremely low as compared with the water quality standards for urban water supply in China, however that of the total THMs is relatively higher and about 2.3%.
