Abstract In this study, we employed the response surface method (RSM) and long short‐term memory (LSTM) model to optimize operational parameters predict chemical oxygen demand (COD) removal in electrocoagulation‐catalytic ozonation process (ECOP) for pharmaceutical wastewater treatment. Through RSM simulation, quantified effects of reaction time, ozone dose, current density, catalyst packed rate on COD removal.

After evaluating ECOP performance under optimized conditions, LSTM predicted (56.4%), close real results (54.6%) with 0.2% error. outperformed predictive capacity initial concentration effluent discharge standards, intelligent adjustment operating becomes feasible, facilitating precise control based model. This strategy holds promise enhancing treatment scenarios. Practitioner Points study utilized optimization. (56.4%) closely matched experimental (54.6%), minimal error 0.2%. demonstrated superior capacity, enabling parameter adjustments enhanced control. Intelligent improving

Real-time control (RTC) can be applied to optimize the operation of anaerobic–anoxic–oxic (A2O) process in wastewater treatment for energy saving. In recent years, many studies have utilized deep reinforcement learning (DRL) construct a novel AI-based RTC system optimizing A2O process. However, existing DRL methods require use mechanistic models training. Therefore they specified data construction models, which is often difficult achieve plants (WWTPs) where collection facilities are inadequate. Also, training time-consuming because it needs multiple simulations model. To address these issues, this study designs data-driven method. The method first creates simulation model using LSTM and an attention module (LSTM-ATT). This established based on flexible from LSTM-ATT simplified version large language (LLM), has much more powerful ability analyzing time-sequence than usual but with small architecture that avoids overfitting dynamic data. Based this, new framework constructed, leveraging rapid computational capabilities accelerate proposed WWTP Western China. An built used train reduction aeration qualified effluent. For simulation, its mean squared error remains between 0.0039 0.0243, while R-squared values larger 0.996. strategy provided by DQN effectively reduces average DO setpoint 3.956 mg/L 3.884 mg/L, acceptable provides pure WWTPs DRL, effective saving consumption reduction. It also demonstrates purely process, providing decision-support management.

Abstract To control water quality and seawater desalination dosage, modeling the coagulation process of saltwater is crucial. With a focus on features with long lag, machine-learning sequence-based approach suggested. The link between influent effluent turbidities, flow rates, flocculant coagulant dosages, other parameters modeled using structured units such as gate recurrent unit encoder linear network decoder. model’s validity confirmed by numerical experiments based real operating data, which also offer solid foundation for managing assistance reduction.
