Abstract

The present invention proposes a sludge bulking suppression method based on self-adaptive segmental sliding mode control, aiming at the problem that abnormal sludge bulking is easy to occur in the sewage treatment process, and it is difficult to transition to normal working conditions, and realizes the suppression of sludge bulking . The present invention adopts fuzzy neural network to obtain water quality parameters in the sewage treatment operation process to predict the sludge volume index in real time to judge the working conditions of the operation process, provide reference signals for the switching of the controller, and design a segmented sliding mode control with an adaptive switching mechanism The device regulates the dissolved oxygen concentration and nitrate nitrogen concentration, coordinates the biochemical reaction process, improves the sludge settling characteristics, and can ensure that the sewage treatment process returns to normal working conditions when sludge bulking occurs.

Description

technical field [0001] The patent of the present invention uses the sludge expansion suppression method based on adaptive segmental sliding mode control to realize the suppression of sludge expansion in the sewage treatment process, and coordinates the biochemical reaction process by adjusting the process variables dissolved oxygen concentration and nitrate nitrogen concentration, so that the sewage treatment process The sludge volume index is an important index to measure sludge bulking, and it is of great significance to predict this index in real time during the control process; to ensure that the sewage treatment process returns to normal working conditions when sludge bulking occurs, both Belongs to the field of water research, but also belongs to the field of intelligent control; Background technique [0002] Water is the most important basic resource for urban development. In recent years, the continuous development of industry has gradually increased the discharge o...
