摘要
随着城市高层建筑的日益增多,如何有效避免二次供水系统中的生活用水污染已成为业界密切关注的问题。在高层住宅二次供水系统中增加二次消毒环节可以降低生活用水的污染风险,文章结合臭氧与紫外线消毒技术,通过模拟测试与实际应用研究二次消毒措施对高层住宅生活用水水质的影响。研究发现,二次消毒措施对水体的pH与浑浊度影响较小,但会造成水体余氯瞬时衰减,且二次消毒措施对水体余氯后续衰减存在抑制作用。据此,文章建立并优化了二次消毒应用策略,为泵房二次供水消毒技术应用提供理论依据与实践经验。
With the increasing number of high-rise buildings in cities,how to effectively avoid domestic water pollution in the secondary water supply system has become an issue that attracted the industry pays close attention.Adding secondary disinfection to the secondary water supply system of high-rise residential buildings could reduce the pollution risk of domestic water.This article had combined ozone and ultraviolet disinfection technology to study the impact of secondary disinfection measures on the quality of domestic water in high-rise residential buildings through simulation tests and practical applications.Studies had found that secondary disinfection measures had little effect on the pH and turbidity of the water body,but would cause the instantaneous attenuation of residual chlorine in the water body.And secondary disinfection measures had an inhibition effect on the subsequent attenuation of residual chlorine in the water body.Based on this,this article had established and optimized the secondary disinfection application strategy,and provided theoretical basis and practical experience for the application of secondary water supply disinfection technology in the pump room.
