Abstract
Disclosed is a method for predicting aeration quantity required to maintain a stable dissolved oxygen concentration in an activated sludge system, including measuring operating parameters of a biochemical tank of a wastewater treatment plant at intervals of a ttime period over a certain period of time; replacing the DO concentration data with DO concentration data after a ttime period from the time of measurement; filtering the DO concentration data after being replaced to form a dataset; building a random forest model, and building a machine learning matrix using data in the dataset to train the random forest model; evaluating prediction performance of the trained random forest model; and using the trained random forest model to predict an aeration airflow rate required to achieve the target DO concentration value after the ttime period, thereby adjusting an aeration airflow rate.
