摘　　要：提出了基于活性污泥处理系统的模型,目的是优化能量消耗和提高废水排出质量。采用ASM1模型来模拟生物反应,对包括硝化、反硝化和曝气等复杂过程的活性污泥废水处理系统进行了模拟和优化研究。对比模拟结果和优化结果得到以下结论:对废水处理过程进行优化后,提高了废水出口质量,出口处的TSS、COD、BOD和TKN全部满足环境标准,同时降低了操作费用(约1/4)。A model based on activated sludge wastewater treatment systems was presented. The objective was to optimize energy consumption and improve effluent quality. Activated Sludge Model No. 1 （ASM1） was used for bioreactor modeling. A case study was made for a complex activated sludge process including nitrification, denitrification and aeration. Optimization waas made for three reactor layouts, the results showed that the quality of effluent was improved, and TSS, COD, BOD and TKN of the effluent all satisfied the environment regulation. At the same time, lower operational costs （mainly pumping energy and aeration energy） were achieved （saving by about 1/4）.
