摘　　要：管网水质安全是供水行业长期关注的重点,管网水质模型通过跟踪、评价、预测管网水质变化,在保障管网水质安全方面发挥了重要作用。由于管网内部环境复杂,管网水质微观机理模型的研究难度较大;但随着数据获取能力和分析能力的不断提高,经验统计模型在管网水质模拟中发挥了越来越重要的作用。首先,简介了经验统计模型的原理、常用变量及建模方法,并对比了几种典型算法的优缺点;其次,分别介绍了各类经验模型的研究进展;最后,对未来研究方向进行了展望。The security of water quality in drinking water distribution systems(DWDSs)is a long-term focus of the water supply industry.Water quality models play an important role in ensuring the DWDSs water quality by tracking,assessing,and predicting water quality changes.Due to the complicated internal environment of DWDSs,it is difficult to establish micro-mechanism models of water quality changes.However,with the rapid improvements of data acquisition and analysis capabilities nowadays,empirical statistic models have played an increasingly important role in water quality modeling.The principle,commonly-used variables and approaches of empirical statistic models are first introduced in this paper,while the advantages and disadvantages of several typical algorithms that are adopted by the models are compared.Furthermore,the research progress on various empirical models is discussed.Finally,the future research directions are prospected.
