由于它们可以缓解大肠菌群再生、味道和气味等水质问题，生物过程很可能成为饮用水处理的重要组成部分。尽管生物膜法生物处理在欧洲得到了广泛应用，并在北美引起了人们的兴趣，但其设计和运行还没有合理的依据。本文分析了用于生物降解有机物硝化和氧化的好氧过滤器的动力学。作者回顾了生物膜动力学的原理，并将这些原理应用于各种生物膜工艺的设计和性能分析。 四个基本参数的识别和标准化加载曲线的使用对分析至关重要。包括16个参考文献、表格和图表。

Because they mitigate water quality problems such as coliform regrowth and tastes and odors, biological processes are likely to become an essential part of drinking water treatment. Although biological treatment with biofilm processes is widely used in Europe and is gaining interest in North America, no rational basis is yet available for its design and operation. This article analyzes the kinetics of aerobic filters used for nitrification and oxidation of biodegradable organic material. The author reviews the principles of biofilm kinetics and applies those principles to analysis of the design and performance of a variety of biofilm processes. Identification of four fundamental parameters and the use of normalized loading curves are critical to the analysis. Includes 16 references, tables, figures.
