Abstract
Provided is an anaerobic digestion process monitoring system for predicting a biogas production amount with high accuracy even when the activity of anaerobic microorganisms in a digestion tank changes. The anaerobic digestion process monitoring system includes: a first sensor which measures a feeding amount of organic waste into a digestion tank and outputs a measurement result as load data; a second sensor which measures a property of a fermented liquid inside the digestion tank and outputs a measurement result as fermented liquid property data; a preprocessing unit which calculates estimate activity index data indicating an anaerobic microorganism activity level from load data and fermented liquid property data, using a first estimation model; and a gas production amount prediction unit which calculates a biogas production amount prediction value from load data, fermented liquid property data, and estimate activity index data, using a second estimation model.
