本幻灯片介绍了微生物和微生物同时存在的问题 分配系统中的消毒剂残留。具体的 目标包括: 评估动态水质的影响 分配系统中微生物失活的条件（悬浮微生物）； 特定消毒剂水平的益处； 消毒剂残留作为微生物检测指标 诚实正直 最低限度的消毒剂残留，以保持微生物 水质； 引起细菌死亡的微生物的浓度 消毒剂残留量明显减少 研究方法包括四个阶段: 重新查看现有信息，包括 文献综述， 建模工作， 公用事业调查，以及， 历史水质数据分析； 确定微生物的灭活潜力 在实验室规模（2项挑战）； 评估急性和慢性水质变化对环境的影响 消毒效果（小型、环形反应器）；和 评估水质变化对环境的影响 中试规模（管道回路）的消毒效果，以及 二级消毒剂的分析局限性。

This slide presentation addresses the problem of the simultaneous presence of microorganisms and disinfectant residuals in distribution systems. Specific goals include: assess the impact of dynamic water quality conditions in distribution systems on microorganism inactivation (microorganisms in suspension); benefits of specific disinfectant levels; disinfectant residual as an indicator of microbial integrity; minimum disinfectant residual to maintain microbial water quality; concentration of microorganisms that induce a measurable decrease in disinfectant residual The research approach consists of four phases: revisit existing information including literature review, modeling effort, utility survey, and, historical water quality data analysis; determine inactivation potential of microorganisms at the bench scale (2 challenges); evaluate impact of acute and chronic water quality changes on disinfection efficacy (bench scale, annular reactors); and, evaluate impact of water quality changes on disinfection efficacy at the pilot scale (pipe loops), and analytical limitations of secondary disinfectant.
