- 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+Fe3O4）>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。
- Abstract:
- 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 of α-FeOOH to γ-FeOOH+β-FeOOH+Fe3O4 was greater than 1, indicating that the UV disinfection and UV/chlorine disinfection inhibited the corrosion of the pipe network.
