Summary: | PURPOSE:To effect an effective prediction and control of activated sludge processing by providing a steady-state analyzing means for computing the state variable containing-controllable factors and a means for computing the optimum solution using the analysis model obtained by the steady-state analyzing means. CONSTITUTION:A prediction and control device is provided with an arithmetic processing part 1 having a steady-state analyzing part 2 and an optimizing part 3, a dynamic simulation part 4 and an activated sludge processing part 5, thereby effecting a model prediction and control of the processing of activated sludge. The steady-state analyzing part 2 is important for grasping the steady- state characteristics of the state variable containing-control factors and as a decisive means for the initial values of an optimized tool and the dynamic simulation. The optimum solution is obtained by the optimizing part 3 setting up evaluation reference and constraint condition and using SIMPLEX method. The dynamic simulation part 4 effects a stabilized control of nitrification in an unsteady-state, since it determines the amt. of air flow and the processing of the excessive sludge. |
