| Abstract |
This study evaluated the removal performance of air precursor substances using a wall drainage panel embedded with coconut shell powder
and zeolite beads in an actual underground parking environment without ultraviolet exposure. The experimental results showed that the
average concentrations of NOX and SOX were highest during periods of heavy vehicle traffic and on days with elevated outdoor fine dust
levels, but decreased by 53% and 51%, respectively, after the installation of the wall panel. The average daily removal efficiencies of NOX
and SOX were 58% and 54%, respectively, and the fine dust grade improved from “poor” to “good.” In addition, both coconut shell powder
and zeolite beads maintained stable removal performance even after nine months of installation. Therefore, the wall drainage panel
incorporating coconut shell powder and zeolite beads is considered an effective and eco-friendly technique for reducing air precursor
pollutants in underground parking facilities. |
