饮用水微生物学家日益关注的一个问题是，由于配水系统内的细菌生长，水质经常恶化。最近的研究表明，分配系统中的细菌生长主要发生在固定在管道内表面的生物膜中。虽然大多数公用事业公司使用氯化来防止和控制分配系统中的生物膜生长，但另一种方法是通过减少限制性营养源来控制细菌生长，这通常是异养细菌生长所需的可生物降解溶解有机碳（BDOC）。本文分析了之前收集的数据，以回答以下问题:采出水中的BDOC水平如何确保水在分配过程中的生物稳定性，以及什么样的水处理能够达到这些BDOC水平。

A growing concern among drinking water microbiologists is the frequent deterioration of water quality due to bacterial growth within distribution systems. It has recently been shown that the growth of bacteria in distribution systems mainly takes place in the biofilm fixed at the internal surface of the pipes. While most utilities use chlorination to prevent and control biofilm growth in distribution systems, an alternative approach is to control bacterial growth by reducing the limiting nutrient source, which is most often biodegradable dissolved organic carbon (BDOC), required for the growth of heterotrophic bacteria. This paper analyzes data previously collected to answer the following: what level of BDOC in produced water ensures the biological stability of the water during distribution, and what kind of water treatment is able to achieve these BDOC levels.
