活性污泥法污水处理数学模型的发展和应用

Development and Application of Activated Sludge Mathematical Models for Wastewater Treatment Process

摘要: 综述了活性污泥法污水处理数学模型自20世纪50年代以来的发展历程；阐述了国际水协会（IWA）推出的活性污泥1号、2号、2D号、3号模型（ASM1、ASM2、ASM2D、ASM3）各自的特点和使用限制条件；介绍了几种基于ASM系列模型的具有代表性的商业化仿真软件．最后，还就ASM系列模型的三个应用难点——水质的分析测定、模型简化、参数校正进行了讨论．

Abstract: This paper summarizes the development of activated sludge mathematical models for wastewater treatment process since 1950s,and presents the characteristics and restrictions of activated sludge models No.1,2,2D and 3(ASM1,ASM2,ASM2D,ASM3) recommended by IWA(International Water Association).Some typical types of commercial simulation softwares based on ASM are described.Finally,three key issues concerning the application of ASM models,i.e.water quality analysis,model simplification and parameters calibration are discussed.
