项目摘要

Recent demands for activated sludge processes inclide introduction of nitrogen and/or phosphorus removal from wastewaters, high performance and compact size, energy saving operation, etc. These highly advanced systems require well organized process control and monitoring, which in turn raise the need for a structured simulation model of activated sludge process. The present study aimed at developing an activated sludge control system based on structured mathematical models. Especially, (1) investigation of process control strategy resulting in development of a practical program for process simulation, and(2) development of man-machine interface which connect process control hardwares and the mathmatical model of activated sludge process, were atempted. As the result, a procerss control system based on the blackboard concept was constructed, in which on-line data, analytical results from chmical laboratory, fassy-expert model and mathematical simulation model are integrated to monitor and control the process. The effectiveness of the system was tested against a high loading nitrogen removal process. In addition, a new simulation program was developed by introducing activated sludge floc structure. By this modification, a better simulation results were obtained for nitrification-denitrification processes.

对活性污泥过程的最新需求涉及从废水中引入氮和/或磷去除，高性能和紧凑型尺寸，节能操作等。这些高级的系统需要组织良好的过程控制和监测，从而增加了对活性污泥过程的结构模拟模型的需求。本研究旨在基于结构化数学模型开发激活的污泥控制系统。尤其是（1）研究过程控制策略的调查，导致开发用于过程模拟的实用程序，以及（2）开发了连接过程控制硬件和活性污泥工艺的数学模型的人机接口的开发。结果，构建了基于黑板概念的ProcersS控制系统，其中集成了在线数据，Chmical实验室，Fassy-Expert模型和数学模拟模型的分析结果以监视和控制该过程。针对高负载氮去除过程测试了系统的有效性。此外，通过引入激活的污泥结构来开发一个新的仿真程序。通过这种修改，获得了硝酸化 - 硝化过程的更好的仿真结果。
