制御装置、制御方法及びコンピュータプログラム
Document Type and Number:
Japanese Patent JP7191708
Kind Code:
B2
Abstract:
To provide a control device, a control method, and a computer program capable of suppressing membrane clogging in a combined sewage treatment system including solid-liquid separation means by a membrane and decomposition means of pollutants by activated sludge.SOLUTION: A control device includes solid-liquid separation means by a membrane and decomposition means of pollutants by activated sludge and used in a water treatment system for purifying treated water flowing into a confluent sewage treatment plant. The control device has a measurement data acquisition part and a control part.The measurement data acquisition part acquires measurement data relating to a water quality or a flow rate of the treated water flowing into the water treatment system. The control part controls an operation of a transfer part which transfers a portion of the treated water mixed with the activated sludge in the decomposition means to the outside of the decomposition means, based on the water quality or the flow rate of the treated water indicated by the measurement data.SELECTED DRAWING: Figure 2
