<p>PURPOSE:To enable control not bringing about the lowering of the quality of treated water during a period forming a self-regression model and to stabilize a system by providing an MLSS objective value adder, a total sludge amt. objective value adder and a dissolved oxygen objective value adder. CONSTITUTION:In this sewage treatment control apparatus equipped with an upper control system using a linear model including even the lower control system related to an activated sludge treatment control apparatus as a part of a treatment apparatus, an MLSS objective adder 45 inputting an MLSS objective value calculated from manual analytical data and the output of the optimizing device 31 of the operation device 27 of the upper control system to output them to an excessive sludge amt. operation device 39 is provided. A total sludge amt. objective value adder 47 inputting a total sludge amt. objective value calculated from the manual analytical data and the output of the optimizing device 31 of the operation device 27 to output them to a return sludge amt. operation device 41 is provided and, further, a dissolved oxygen objective value adder 49 inputting a dissolved oxygen objective value calculated from the manual analytical data and the output of the optimizing device 49 to output them to an aeration air amt. operation device 43 is provided.</p> |
