活性污泥法数学模型研究与应用进展

20世纪50年代以来,活性污泥法数学模型的研究取得了重大进展,它在污水处理厂的设计、运行和管理等方面发挥着日益重要的作用。本文从模型的机理、功能和应用等方面进行了全面的综述,详细介绍了发展进程中具有重要意义的几种模型,分析比较了各自的优点和不足。最后分析讨论了ASM数学模型研究与应用中存在的问题,提出了今后活性污泥法模型和软件可能的研究方向和发展趋势。

Advances of study and application for activated sludge models

The study on activated sludge models has achieved great advances since 1950s. The models are playing more and more important roles in the design, operation and administration of the wastewater treatment plants. The development of activated sludge models is reviewed and discussed from the mechanism, function and application. Several important models are introduced in detail, the advantage and disadvantage of which are compared. Finally, some important problems that should be solved for ASM models are discussed, and future investigation and applications of the activated sludge models and process software are presented.
