Summary: The Fe-rich biochar produced by the co-hydrothermal treatment of red mud and reed straw, as a novel sludge conditioner, activates H2O2 to improve sludge dewaterability through heterogeneous and homogeneous Fenton reactions. The double Fenton reaction enhances the production efficiency of (center dot OH), disperses sludge flocs into smaller particles, and releases more bound water from extracellular polymeric substances (EPS), thus improving sludge dewaterability. Additionally, using the Fe3O4 supported in the biochar structure as a catalyst and employing Fe2+ leached from biochar for homogeneous reaction contribute to the overall improvement in sludge conditioning.

Summary: In this study, the feasibility of using Schwertmannite-composited Fe3O4 as a heterogeneous Fenton catalyst to enhance sludge dewaterability without the need for pH adjustment was investigated. The results showed that the Sch/Fe3O4 +H2O2 treatment effectively reduced the sludge specific resistance to filtration, moisture content, and bound water without acidification. The generation of SO42- and H+ in the Sch/Fe3O4 system played a crucial role in sludge pH decrease, facilitating sludge cell lysis and water release.

Summary: In this study, ascorbic acid was introduced as a reducing/chelating agent in the traditional Fe-0/PS process for sludge dewatering, leading to significant improvement in dewatering performance and oxidation efficiency. The improvement can be attributed to the reduction and chelating capacity of ascorbic acid, as well as the destruction of proteinaceous components and humic substances in sludge EPS by free radicals produced in the process, resulting in improved rheological properties of the sludge.

Summary: Chemical sulfidation is effective in improving the reactivity of zero-valent iron (S-ZVI). Inspired by the biogeochemical process of sulfidation in nature, researchers explored the biogenetic sulfidation of ZVI (BS-ZVI) using sulfate-reducing bacteria (SRB). BS-ZVI showed a degradation rate of 96.3% for trichloroethylene (TCE), comparable to S-ZVI (97.0%), but with a slower degradation rate due to extracellular polymeric substances (EPS) excreted by SRB. Organic components of EPS, including polysaccharides, humic acid-like substances, and proteins, were detected in BS-ZVI. The acetylation degree of EPS increased with ZVI and S/Fe concentration, inhibiting TCE degradation. Overall, this study demonstrated the potential of biogenetic sulfidation as an alternative method for improving the reactivity of ZVI.

Summary: This study investigated the abiotic transformations of the antibiotic sulfamethoxazole (SMX) by intermediates produced during biological nitrogen removal processes, including hydroxylamine (NH2OH), nitrite (NO2-), and nitric oxide (NO). The results showed that while NH2OH was not directly able to transform SMX, NO2- and NO could chemically transform SMX through various reactions. The study also determined the rate constants of SMX with NO2- and NO under different pH and oxygen conditions. The findings enhance our understanding of antibiotic fate during biological nitrogen removal and emphasize the role of reactive nitrogen species in antibiotic degradation.

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.
