Recent years, advanced treament like nitrogen or phosphate removal has been required in the activated sludge process, thus optimization of the desgn and control of these processes is now demanded. For that purpose we need simulation models which can predict the process behavior properly. In the present research, we intended to develop an activated sludge model to be used for process design and control based on the IAWQ Activated Sludge Model No.2, which has been recognized as the most reliable activated sludge model. Major research topics include : 1) development of a basic simulation model, 2) calibration of the model using actual operation data from different wastewater treatment plants, 3) determination of decay coefficient for glycogen-an essential intracellular storage polymer in biological phosphate removal systems and 4) estimation of kinetics and rate of slowly biodegradable organic substrate hydrolysis. Basic parts of the simulation system were developed, but human interface is to be furher developed and detailed kinetics of the hydrolysis process be investigated in the future.

近年来，活性污泥法对除氮、除磷等高级处理提出了更高的要求，这就要求对这些工艺的设计和控制进行优化。为此，我们需要能够正确预测进程行为的仿真模型。在这项研究中，我们打算在IAWQ活性污泥模型2号的基础上开发一个用于工艺设计和控制的活性污泥模型，该模型被认为是最可靠的活性污泥模型。主要研究内容包括：1)建立基本的模拟模型，2)利用不同污水处理厂的实际运行数据对模型进行校准，3)测定生物除磷系统中必需的胞内储存聚合物--糖原的衰减系数，4)估计缓慢可生物降解的有机底物的降解动力学和速率。模拟系统的基本部分已经开发完成，但人机界面还有待进一步开发，详细的动力学研究还有待于进一步研究。
