Summary: The mechanisms of utilizing refractory organic matter (ROM) as an inner carbon source for advanced nitrogen and organic matter removal were systematically analyzed in this study. Without any external carbon source, a high removal efficiency of total nitrogen and organic carbon was achieved. The study also observed an increase in the abundance of bacteria capable of degrading ROM, indicating the potential for synchronous advanced nitrogen and organic matter removal from mature landfill leachate.

Summary: Due to the lack of biodegradable organic matter in mature landfill leachate, refractory dissolved organic matter has been utilized as a potential carbon source for denitrification. Several methods to improve the biodegradability of this refractory dissolved organic matter have been summarized. Furthermore, a novel integrated anammox-based process has been proposed for mature landfill leachate treatment, which can achieve advanced nitrogen removal in a more economical and environmentally effective way.

Summary: The study demonstrated the potential of a one-stage partial nitrification-Anammox process (PNA) to effectively remove nitrogen and organics from leachate, with up to 96% of total nitrogen and 43% of COD being removed. Fluorescence analysis revealed insights into the dynamics of influent fluorophores, seasonal variations, and the preferential removal of protein-like compounds. Oxygen supply was found to promote the degradation of protein-like compounds, with potential implications for aerobic oxidation pathways. Additionally, fluorescence was suggested as a potential indicator for biodegradable organics, showing strong correlations with biodegradable chemical oxidation demand (BCOD).

Summary: The efficiency and mechanism of the UV/nFe(0)/H2O2 system in removing refractory organics from membrane bioreactor effluent were investigated. Under certain conditions, the system effectively removed organics and reduced their properties. Various iron-based oxides were formed on the surface of nano zero-valent iron, which contributed to the removal of refractory organics. UV radiation enhanced the redox cycle of iron, thereby enhancing the removal of organics.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
