摘　　要：为了了解不同消毒方式(紫外消毒、紫外-氯联合消毒、氯消毒)对管段出水水质及管段腐蚀的影响,在某水厂构建了一套管网系统中试装置进行研究。根据管垢形貌特征的变化发现,氯消毒方式下管垢的形成时间比紫外-氯消毒方式下要短;另外,管垢组分分析结果显示,在紫外消毒和紫外-氯联合消毒两种方式下,管垢各组分之间存在α-FeOOH/(γ-FeOOH+β-FeOOH+Fe_(3)O_(4))>1的关系,这表明紫外消毒和紫外-氯消毒两种方式可抑制管网腐蚀。A pilot-scale device of pipe network system was constructed in a water treatment plant in order to investigate the influence of different disinfection methods(UV disinfection,UV/chlorine disinfection and chlorination)on the drinking water quality and pipe corrosion.According to the morphological characteristics of the pipe scale,the scale formation time of chlorination was shorter than that of UV/chlorine disinfection.In addition,the analysis of pipe scale components in both UV disinfection and UV/chlorine disinfection showed that the ratio ofα-FeOOH toγ-FeOOH+β-FeOOH+Fe_(3)O_(4) was greater than 1,indicating that the UV disinfection and UV/chlorine disinfection inhibited the corrosion of the pipe network.
