通过控制细菌数量限制微生物生长 营养素已经被很好地研究用于异养 细菌，但很少有研究 用这种方法控制土壤中的硝化菌 饮用水。本研究的目的 是为了调查大量营养素的影响， 微量营养物质和管道材料 模拟条件下的硝化活性 管道状况。 硝化作用在不同的环境中会有很大的变化 分配系统，取决于管道 使用的材料和存在的营养素。 关注硝化作用影响的公用事业公司 我们应该检查分布的极端情况 系统，包括房屋管道 系统，以描述所有可能的 影响。水供应商可以使用结果 指导抽样和检测部分分布 最容易受到影响的系统 硝化细菌的生长。硝化作用的控制 对公众来说是一个复杂的问题 健康影响，所以这些知识将 有助于全面规划 分销系统的管理。包括45个参考文献、表格和图表。

Limiting microbial growth via control of nutrients has been well studied for heterotrophic bacteria, but there are few studies on this approach for control of nitrifiers in drinking water. The objective of this study was to investigate the impact of macronutrients, trace nutrients, and pipe materials on nitrification activity under simulated premise plumbing conditions. Nitrification can vary dramatically in a distribution system, depending on the pipe materials used and the nutrients that are present. Utilities concerned about effects of nitrification should examine extremes of the distribution system, including premise plumbing systems, to characterize the full range of possible effects. Water suppliers can use the results to guide sampling and detect parts of the distribution system that are most susceptible to growth of nitrifying bacteria. Control of nitrification is a complex problem with public health implications, so this knowledge will be helpful in planning holistic and comprehensive management of distribution systems.Includes 45 references, tables, figures.
