摘　　要：管网水质模型是评价供水管网水质、预测水质变化的有效工具。随着管网水质变化机理研究的不断深入,水质模型也不断完善。其中,微观机理模型是一个重要分支,因此有必要重点关注管网水质变化的影响因素及其机理。首先,以余氯衰减模型为例,介绍了模拟单一化学物质转化的微观机理模型的原理;其次,基于余氯衰减、消毒副产物生成、微生物生长模型,重点论述了模拟多物质反应过程的微观机理模型的研究进展;最后,总结了微观机理模型的应用。Water quality model is an effective tool to evaluate the water quality and predict the water quality changes in drinking water distribution systems(DWDSs).The models are constantly improved with a continuous research progress on water quality change mechanism in DWDSs.Among the available models,the micro-mechanism models represent an important branch,which primarily focus on the influencing factors and the mechanism of water quality changes.The principle of micro-mechanism models that simulate the fate of a single chemical is first introduced by taking chlorine residual decay models as examples;and then,the latest research progress on micro-mechanism models that simulate multiple interactive chemical species is discussed based on chlorine residuals decay,disinfection by-products formation and microorganisms growing models;finally,the application of micro-mechanism models to DWDSs is summarized.
