Abstract
In terms of construction and maintenance costs, granular bed filters offer notable advantages over existing pollutant desorption technology methods. Achieving synergistic removal of PM2.5 and CO2 through a multideck granular bed is possible by incorporating an activated carbon deck between the granular bed decks. During the experimental process, the average PM2.5 filtration efficiency exceeds 95%, while the average CO2 adsorption efficiency surpasses 80%. Substituting activated carbon for one or more decks within the multideck bed during the synergistic removal process offers the dual benefit: (1) preventing PM2.5 from interfering with CO2 adsorption by the activated carbon; (2) the internal pore specific surface area advantage of the activated carbon bed can also provide an auxiliary adsorption effect when filtering PM2.5. In addition, the granular bed showed a good synergistic regeneration performance. Consequently, this study introduces a new technological approach for the synergistic separation of PM2.5 and CO2, which informs the application of particulate bed filtration for the synergistic uptake of multiple pollutants.
