英文摘要 | In this study, a combined alkaline (ALK) and ultrasonication (ULS) sludge lysis-cryptic pretreatment and anoxic/oxic (AO) system (AO ALK/ULS) was developed to enhance biological nitrogen removal (BNR) in domestic wastewater with a low carbon/nitrogen (C/N) ratio. A real-time control strategy for the AO ALK/ULS system was designed to optimize the sludge lysate return ratio (R-SLR) under variable sludge concentrations and variations in the influent C/N (<= 5). A multi-layered backpropagation artificial neural network (BPANN) model with network topology of 1 input layer, 3 hidden layers, and 1 output layer, using the Levenberg-Marquardt algorithm, was developed and validated. Experimental and predicted data showed significant concurrence, verified with a high regression coefficient (R-2 = 0.9513) and accuracy of the BPANN. The BPANN model effectively captured the complex nonlinear relationships between the related input variables and effluent output in the combined lysis-cryptic BNR system. The model could be used to support the real-time dynamic response and process optimization control to treat low C/N domestic wastewater. (C) 2020 Elsevier Ltd. All rights reserved. |
