【摘要】 以建立给水处理过程的风险分析方法为目标,提出了综合考虑余氯、氨氮、溴离子、有机物相互关系的预氯化工艺概率机理模型.以典型给水处理厂的现场监测数据为基础,对模型参数进行了率定,并验证了模型的模拟效果.该模型能够较好地模拟预氯化工艺中高锰酸盐指数、氨氮以及氯仿、一溴二氯甲烷、二溴一氯甲烷和溴仿4种消毒副产物的浓度概率分布.更多还原

【Abstract】 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.更多还原
