随着美国环境保护局1989年大肠菌群规则要求的监测变化，成品饮用水中大肠菌群再生相关的问题正在增加。本文综述了再生长现象的类型以及分配系统管道中再生长的分析证据。它还考虑了影响细菌再生的因素，包括环境因素、细菌营养素、消毒剂残留、腐蚀和沉积物累积以及水力效应。研究了控制细菌再生的方法，包括有效处理和监测、冲洗和机械清洗、消毒、腐蚀控制和营养控制，以及- -并讨论了关于使用生物处理的担忧。包括166篇参考文献、图表。

With monitoring changes required by the US Environmental Protection Agency's 1989 coliform rule, the problems associated with coliform regrowth in finished drinking water are increasing. This article reviews the types of regrowth phenomena and the analytical evidence for regrowth in distribution system pipelines. It also considers factors that influence bacterial regrowth, including environmental factors, bacterial nutrients, disinfectant residuals, corrosion and sediment accumulation, and hydraulic effects. Methods for controlling bacterial regrowth, including effective treatment and monitoring, flushing and mechanical cleaning, disinfection, corrosion control, and nutrient control, are examined, and the advantages of--and concerns about--using biological treatment are discussed. Includes 166 references, figures.
