To enhance the CO2 adsorption capacity of bamboo biochar, anaerobic microorganisms were used to treat bamboo biochar. This study investigated the effects of microbial treatment time (1-4 weeks) on the pore structure of biochar and its CO2 adsorption performance. The results showed that microbial treatment significantly improved the pore structure of biochar: after 2 weeks of treatment, the specific surface area increased from 182.36 m2/g to 288.93 m2/g. However, an excessively long treatment time led to a decrease in the specific surface area; after 4 weeks of treatment, the specific surface area of MBC-4 dropped to 121.10 m2/g. After microbial treatment, the biochar exhibited better CO2 adsorption performance, with the adsorption capacity increasing from 42.36 mg/g to 48.28 mg/g, representing a 14% increase compared to the original bamboo biochar. The adsorption process of CO2 by biochar was studied using pseudo-first-order and pseudo-second-order kinetic models. It was found that the pseudo-second-order kinetic model could better describe the CO2 adsorption by biochar, indicating that in addition to physical adsorption, chemical adsorption also occurred in the CO2 adsorption process by biochar. In addition, the Langmuir model is more suitable for fitting the adsorption of CO2 by biochar than the Freundlich model. %K 生物炭， %K 微生物处理， %K 吸附， %K CO2
