摘要： PURPOSE:To aim at the production of a constantly good treated water by preventing nitrification efficiency from being decreased by reductions in the temperature of a nitrification tank through the attainment of the target value of sludge quantity preset according to the tank temperatures and correcting the sludge quantity target value through the measurement of ammonia concentration in the nitrification tank. CONSTITUTION:Waste water is subjected to a biological nitrification/ denitrification in a plant system comprising a nitrification tank 2, denitrification tank 7 and sedimentation basin 3. In a sludge quantity target value calculation portion 18, the target value Wtsv of the quantity of an activated sludge in the system is calculated from the temperatures of the nitrification tank 2. In a sludge quantity target value correction portion 19, the correction value of the targeted activated sludge quantity in the system is calculated from ammonia concentration at an outlet portion of the nitrification tank 2. Moreover, a sludge quantity controller 20 controls the sludge quantity to attain the target value. As a result, a reduction in the nitrification efficiency due to reductions in the temperatures and variations in the load can be prevented and a constantly good treated water can be produced.

摘要： PURPOSE:To attain the control of the number of pump groups with high reliability by obtaining the evaluation value of the start/stop control of the pump groups after performing a fuzzy inference in terms of the obtained estimated value of the inflow rate and the estimated maximum and minimum water levels. CONSTITUTION:An inflow rate estimating part 11 estimates an inflow rate from the input water level and total pumping volume. A water level estimating part 12 finds the minimum and maximum water levels at a prescribed time. A pre-processing part 14 operates the input value of a fuzzy inference from the minimum and maximum vater level and the estimated value of the inflow rote. A fuzzy inferring part 13 applies a fuzzy inference to the evaluation value of the pump start/stop control based on the input value obtained at the part 14 and by reference to a fuzzy rule stored in a knowledge base 16. A start/stop deciding part 17 decides the start/stop of a pump based on the obtained fuzzy inference result. A target water level arithmetic part 18 operates the target water level in response to the start/stop level set for each pump and gives this target level to a PI control arithmetic part 19. Thus the target speed control value of the pump is operated at the part 19. Then the pump speed is controlled.

摘要： PURPOSE:To eliminate the anxiety of an operator against the automatic control and to reflect the operator's will onto the control by reporting the decided process value of a future time, manipulated variable, and application of the estimated target value to the operator. CONSTITUTION:A controller 2 monitors the process value obtained in real time and also controls the start and the stop of a pump when the pump start/stop water levels exceed the number of pumps. At the same time, an operating plan which is previously produced by an operator is stored in a knowledge base 11 as a strategy knowledge in order to ensure the reflection of the operator's will. A strategy part 4 infers the estimated target value to prescribe the action of a controller 3 at a future time point based on the inputted process value and the operating plan of the base 11. Then the part 4 reports the inferred target value to the operator. Thus the operator can eliminate his/her anxiety against the automatic control and reflect his/her will onto the control.

摘要： PURPOSE: To perform stable sewage treatment by detecting the MLSS and the concn. of return sludge in an aeration tank, and controlling the amt. of return sludge in such a way that the max. value and min. value of the MLSS in a certain time are within a set range.
CONSTITUTION: Sewage (a) is flowed into an aeration tank 1; at the same time, the return sludge (b) in a final settling basin 2 is returned by a pump 3 into the tank 1. Excess sludge (c) is withdrawn with a pump 4. The MLSS of the tank 1 is detected with an MLSS meter 5, and the detected value is inputted to the 1st operator 8, by which whether the MLSS value is within a preset permissible range or not is checked. If it is out of the range, the output signal conforming to the input change is inputted to the 2nd operator 9. The output of the increase or decrease is inputted to a controller 10 for operation of the return sludge pump until there is no more deviation between the target flow rate Qr of return sludge calculated by the 2nd operator 9 and the actual flow rate Qr' of return sludge from the flowmeter 7, and the output signal thereof is stabilized by zero deviation.
