摘要
通过介绍前国际水质协会 (IAWQ)最新推出的第三套活性污泥法动力学模型 (ASM3) ,来探讨活性污泥法动力学模型的发展。ASM3进一步弥补了其前身ASM 1的不足与缺陷 ,更适合于编制计算机代码。ASM 3可以预测活性污泥系统的耗氧量、污泥产量、硝化和反硝化。在ASM 3中 ,衰减 (溶菌 )过程是以内源呼吸理论为基础的。ASM3强调了转换系数和胞内贮存物的重要性。
In this paper, we introduced the development of activated sludge model No. 3(ASM3): it related to the activated sludge model No. l(ASM1) and corrected for some defects of ASM1, and it is provided as a reference in a form which can be implemented in a computer code without further adjustments. ASM3 can predict oxygen consumption, sludge production, nitrification and denitrification of activated sludge systems. ASM3 is based on Endogenous Respiration and it emphasized on the storage of organic substrates and composition matrix. Established on reasonably theoretical basis, ASM3 combines tightly with practice and has been simplified to some extent. This is also the development direction of the activated sludge model.
