Tannic acid (TA), a prevalent polyphenolic contaminant in industrial effluents, significantly inhibits microbial activity anaerobic digestion, thereby diminishing wastewater treatment efficiency. In this study, sulfidized nano zero-valent iron (S-nZVI) composite incorporated into sludge biochar (SB), abbreviated as SB-S-nZVI, was synthesized via one-step hydrothermal method. The composite’s adsorption capacity for TA and its impact on digestion were systematically evaluated. Experimental results showed that SB-S-nZVI achieved removal efficiency of 99.31% under optimal conditions (S/Fe = 0.05, dosage 0.3 g·L−1), with maximum 337.08 mg·g−1. the addition 0.03 g·L−1 enhanced chemical oxygen demand (COD) by 3.32%, increased specific methanogenic 62.66%, improved community composition, particularly enriching hydrolytic bacteria (Georgenia) archaea (Methanosaeta). mechanistic analysis revealed FeS protective layer inhibited oxidation facilitated chemisorption-driven removal. This study presents an innovative approach integrated TA-contaminated combining adsorption, degradation, energy recovery.
