摘要：Lignin, with its intrinsic polyphenolic structure, high carbon content, and diverse functional groups, has emerged as promising precursor for carbon-based materials in pollutant elimination. In this work, lignin-biochar (LC) was fabricated and integrated into LC/ZnAl2O4/Bi2MoO6 composites with adsorption-photocatalysis synergy, employed within an intimate coupling of photocatalysis and biodegradation (ICPB) system for AOX degradation. The formation of Bi-O-C bonds between lignin-biochar and Bi2MoO6 provides atomic-level channel for accelerating electron transfer. Notably, the 1 wt%LC/0.5 wt%ZnAl2O4/Bi2MoO6 (LM3) sample showed superior degradation efficiency, with the apparent rate constants of 13.82-fold (methylene blue, MB) and 5.56-fold (pchlorophenol, 4-CP) higher than those of the pristine Bi2MoO6, respectively. DFT analyses demonstrated strong chemical adsorption interactions between 4-CP and lignin-biochar, with the highest adsorption energy of -46.3152 eV observed for LC/ZnAl2O4/Bi2MoO6. The synergistic adsorption-photocatalysis mechanism of the LC/ZnAl2O4/Bi2MoO6 composite was systematically explored, highlighting the critical role of lignin-biochar in enhancing adsorption, charge separation, and reactive oxygen species generation. The ICPB system demonstrated effective degradation of refractory 4-CP and bamboo ECF bleaching effluent. The visible-light driven ICPB system (VCPB) achieved 78.30 % TOC removal for 4-CP effluent within 24 h. Furthermore, the VCPB process achieved 80.03 % COD and 71.03 % AOX removals for an industrial bamboo ECF bleaching effluent sample, with longterm operational stability, while fostering robust microbial activity and enhanced biofilm diversity. The synergistic mechanism of the system between adsorption, photocatalysis, and biodegradation was discussed. This work provides a novel approach for designing bio-based photocatalysts for the degradation of refractory industrial effluents.
