The Research On Modeling And Control For A～2/O Technics Of Wastewater Treatment Based On ASM2

Now, the Activated Sludge Process, a kind of wastewater treatment with complicated mechanism, non-linear and varying, has been extensively utilized in the industrial and municipal wastewater treatment. This way has many difficulties in design, run management and control. So, the method of activated sludge model and real time monitor system is very important, which improves effect of wastewater treatment and manage of manufacture.Nowadays, the society pays more attention on environment protection. As remove of organic matter, the request of remove of Nitrogen and Phosphorus is becoming stricter and stricter. So, based on the Activated Sludge Process with the ASM2 model of remove of Nitrogen and Phosphorus, it is necessary to create a model depended on concrete request of technology process to adapt the application need. The main research work are as follows:1 This paper summarized the meaning in recycling the wastewater and the research value of wastewater process model. It also introduced the domestic and international actuality of automatic control system, and the basic tactic of wastewater process control.2 This paper introduced the principle and process of activated sludge process, and make detailed introduce for its typical technique (A~2/O). It also simply introduced some Activated Sludge Process.3 Based on the detailed introduction of ASM2 model, we simplified the coefficient of equation and derived the general equation of speed of response. At the same time, aiming at the theory of A~2/O technology process, this paper proposed supposing and simplified the equation's parameter and dimension. Furthermore, this paper derived the Mechanism model of A~2/O technology process and made emulation and analysis to the model.4 Based on an concrete project, this paper introduced the automatic control and monitor system. The key descriptions are about the configuration of PC and the composing of network,...
