Summary: This study investigated the microbial community dynamics of a full-scale activated sludge process treating optoelectronic wastewater using NGS technology. It was found that during the low-performance period, bacteria genera resistant to ionizing radiation and those capable of degrading aromatic compounds had lower diversity and abundance. The high-performance period showed shorter average path length and network diameter in microbial taxon co-occurrence network analysis, indicating efficient information dissemination among taxa.

Summary: The study found that the aerobic granular sludge system exhibits long-term stability and is not significantly affected by the randomness of granulation. While the process of granulation can lead to a reduction in microbial richness and diversity, it does not negatively impact wastewater treatment performance. Certain microbial species play crucial roles in the aerobic granular system, contributing to its long-term stability.

Summary: In this study, the dynamics of microbial and viral communities in an expanded granular sludge bed (EGSB) reactor were investigated. The results showed that COD, VSS/TSS ratio, and temperature were the main factors affecting the microbial community structure. The study also identified key genes involved in nitrogen cycling, with the dissimilatory nitrate reduction to ammonia (DNRA) and denitrification pathways dominating in the anaerobic system. The findings provide insights for the optimization of engineered systems.

Summary: HMF deteriorates the removal performance of activated sludge, reducing the removal rates of COD, TP and NH4+-N, while increasing EPS content and affecting the settleability and dewatering capacity of activated sludge. HMF also inhibits dehydrogenase activity in activated sludge and alters microbial functions. Microbial community analysis shows that some microbes are adversely affected by HMF while others better tolerate it.

The satisfaction of farmers with the treatment effect of heavy metal pollution and their income increased. The study found that education level and pollution degree have a positive influence on satisfaction and income, while family income has a negative influence. Age level has a positive influence on satisfaction but a negative influence on income.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
