Morphological and optical analyses confirmed the deposition of CoNi-MOF on the MoS₂ surface. The resulting binary CoNi-MOF/MoS₂ nanocomposite exhibited remarkable photocatalytic activity, achieving degradation efficiencies of 98 % for MV and 92 % for TC, significantly outperforming individual Co-MOF and CoNi-MOF catalysts. Under visible light irradiation, the degradation time was notably reduced compared to UV light irradiation, highlighting the material's superior activity in the visible light range. Subsequently, MoS₂ played a pivotal role as a template that accelerated the separation of electron-hole pairs, while the binary metal organic framework acted as an electron sink, enhancing interfacial charge transfer and promoting the degradation of antibiotics and dyes.

Through parallel factor analysis in conjunction with the self-organizing map algorithm, it was observed that the MCUM primarily degraded aromatic, high MW fluorescent components, while tryptophan-like substances remained as dominant residues due to their resistance to photodegradation. Additionally, the improved surface roughness and hydrophilicity of the MCUM facilitated fouling mitigation by strengthening interfacial repulsion, which diminished foulant adhesion. The fouling mechanism transitioned from complete and intermediate blocking to predominantly intermediate blocking, accompanied by a reduction in gel layer fouling. Consequently, the reversible fouling resistance of the MCUM was reduced by 76.8 %, and the irreversible resistance by 34.3 %, markedly enhancing antifouling performance.

Microalgal-bacterial granular sludge (MBGS) has emerged as a sustainable and efficient technology for domestic wastewater treatment. Nonetheless, the effects of residual LCM on MBGS performance remains largely unexplored. This study examined the impact of varying LCM concentrations on MBGS under simulated domestic wastewater treatment conditions. Our results indicated that 10 mg/L LCM concentrations stimulated MBGS to secrete extracellular polymeric substances (EPS), thereby enhancing both adsorption and biodegradation of LCM. Nevertheless, LCM exposure impaired MBGS efficiency, notably in water treatment and nitrogen cycling processes. Amplicon sequencing revealed that the deterioration of wastewater-treatment efficiency was associated with a reduced abundance of cyanobacteria and bdelloidea. Moreover, metagenomic analysis corroborated that LCM exposure diminished cyanobacteria abundance and highlighted the pivotal role of cyanobacteria in both nitrogen assimilation and dissimilation. LCM exposure impaired nitrogen cycling efficiency, disrupting the production of cofactors production and vitamin metabolism. Furthermore, LCM induced an increase in antibiotic resistance genes (ARGs), which may support MBGS survival under antibiotic stress. This study provides a comprehensive elucidation of the multifaceted impact mechanisms of LCM on MBGS. Additionally, it highlights the critical role of cyanobacteria in nitrogen cycling and their susceptibility to LCM exposure, thereby offering insights into the ecological ramifications of antibiotic pollution in wastewater treatment systems.

Dissolved oxygen (DO) and chlorophyll-a (Chl-a) are essential indicators for evaluating ecosystem stability and water quality. In this study, an innovative and robust intelligent framework is designed using integrated uncertainty quantification and feature selection to predict DO, Chl-a, and bloom risk evaluation of dams. First, the individual machine learning and deep learning models, including Extreme Gradient Boosting (XGBoost), Convolutional Neural Networks (CNNs), Gated Recurrent Units (GRUs), Least Square Support Vector Regression (LSSVR), and Multi-Layer Perceptron (MLP) were assessed. Subsequently, the most effective models are then integrated to enhance predictive accuracy. The Boruta Feature Selection Approach (BFSA), Gamma Test, and Shapley Additive Explanations (SHAP) are used to select the most suitable and relevant features. Then the Monte-Carlo simulation is implemented for uncertainty analysis to evaluate the reliability of models' prediction by determining probability distribution functions. The hybrid XGBoost-CNNs achieved the highest performance in terms of R² = 0.923, RMSE = 0.547 μg/l for Chl-a prediction, and CNNs obtained R² = 0.995, RMSE = 0.143 ppm for DO prediction.
