【摘要】 城市污水厂现行的设计方式还是以实验模拟为主,周期长、耗资大,利用活性污泥数学模型可以快速准确的比较多种处理工艺和设计参数,易于在大范围的方案比较中实现优化。本文介绍了国际上最具影响的ASM系列活性污泥模型,并举例对单级曝气工艺、缺氧/好氧工艺、接触稳定工艺和氧化沟工艺进行了对比,说明了活性污泥数学模型在污水处理厂设计中的应用。更多还原

【Abstract】 The design of wastewater treatment plants (WWTP) is depending on experimental simulation, which costs money and long time. However wastewater treatment processes and their operation conditions can be compared much more easily by using activated sludge mathematical models, thus the design can be optimized in a larger field. In this paper the world’ s most influential models-ASM are briefly introduced, an example is also given to compare 4 typical treatment processes: aerobic only, anoxic and aerobic both, oxidize channel, contact stabilization process, which shows how a mathematical model is used to advise on WWTP design.更多还原
