The research presented herein explores the development of a novel iron-carbon composite, designed specifically for improved treatment high-concentration antibiotic wastewater. Employing nitrogen-shielded thermal calcination approach, investigation utilizes blend reductive iron powder, activated carbon, bentonite, copper manganese dioxide, and ferric oxide to formulate an efficient composite. oxygen exclusion process in particles results distinctive electrochemical cells formation, markedly enhancing wastewater degradation efficiency. Iron-carbon micro-electrolysis not only boosts biochemical degradability concentrated but also mitigates acute biological toxicity. In response increased Fe2+ levels found wastewater, this incorporates Fenton oxidation advanced byproducts. Through synergistic application oxidation, accomplishes significant decrease initial COD reducing them from 90000 mg/L about 30000 mg/L, thus achieving impressive removal efficiency 66.9%. This integrated methodology effectively reduces pollutant load, recycling additionally contributes reduction both volume cost associated with solid waste treatment. underscores considerable potential composite material efficiently managing thereby making notable contribution field environmental science.

Abstract. Microbial fuel cell (MFC) is an efficient in-situ approach to combat pollutants and generate electricity. This study constructed a soil MFC (SMFC) reduce Cr(VI) in paddy investigate its influence on microbial community resistance characteristics. Fe3O4 nanoparticle as the cathodic catalyst effectively boosted power generation (0.97 V, 102.0 mW/m2), whose porous structure reducibility also contributed Cr reduction immobilization. After 30 days, 93.67 % of was eliminated. The bioavailable decreased by 97.44 while residual form increased 88.89 %. SMFC operation greatly changed enzymatic activity structure, with exoelectrogens like Desulfotomaculum (3.32 anode) Cr(VI)-reducing bacteria Hydrogenophaga (2.07 cathode) more than 1000 folds soil. In particular, significantly enhanced abundance heavy metal genes (HRGs). Among them, chrA, chrB, chrR 99.54~3314.34 anode control, probably attributed enrichment potential tolerators Acinetobacter, Limnohabitans, and Desulfotomaculum. These key taxa were positively correlated HRGs but negatively pH, EC, Cr(VI), which could have driven reduction. provided novel evidence for bioelectrochemical system application contaminated soil, be environmental remediation detoxification.
