Effective management of food waste (FW) is essential for achieving energy self-sufficiency and carbon neutrality in treatment plants (FWTPs). Developing a multitandem efficient FW process crucial performing more recovery at on-site plants. In this study, cascading was developed to treat from generation complete disposal. Compared with the unpretreated (UP-FW), enzymolysis exhibited higher hydrolysis efficiencies FW. Specifically, concentrations glucose, chemical oxygen demand, total organic increased by 259.42%, 49.31%, 33.08%, respectively. The pretreated considerable hydrogen yield 35.81 ± 1.47 mL/g-VS, roughly double that raw used as substrate, which also accompanied 26.52% 19.10% increases ethanol acetate production, recyclable catalyst (FRB800) pyrolyzed fermentation residue showed superior Orange G (OG) removal efficiency better anti-interference ability actual water body. OG could be completely removed within 30 min, dominated singlet oxygen, nonradical pathways, diverse active sites on FRB800. This synchronizes resources degradation pollutants. Overall, these findings indicate an alternative approach disposal possesses significant engineering value broad application prospects FWTPs.

Microaeration has been reported to improve anaerobic digestion, which is generally attributed increased microbial diversity, but a thorough explanation lacking. In this study, it was found that intermittent microaeration (IMA) supplied an digester could oxidize Fe(II) produced by dissimilatory iron reduction (DIR) form Fe(III)/Fe(II) cycle and generate extracellular reactive oxygen species (ROS) treatment of phenol-containing wastewater. The results showed compared the control group without IMA, removal rates COD phenol 29.54 49.68 percentage points, respectively, daily average methane production 85.44%. slowed down loss (13.97%) released from sludge due lower solubility Fe(III) facilitated •OH generation (1.22 ± 0.04 μM) via Fenton-like reactions. DIR accelerated degradation. Metagenomic analysis revealed abundance methanogens antioxidant enzymes-encoding genes in response oxidative stress significantly IMA control, enabling methanogenesis proceed smoothly under microaeration. This study investigated ROS induced during digestion their roles promoting performance, thereby providing new perspective for optimizing systems with
