| 摘要 |
The present invention relates to a system (1) and to a method for collecting chemical compound(s) in aggregate (S), characterized in that it comprises at least one surface on which is placed at least one geocomposite (2) comprising at least one draining layer (22) on which there are perforated mini-drains (23) each containing at least one chemical compound fixing filament (24), aggregate (S) being placed on said geocomposite (2) in such a way that a fluid (L), which becomes laden with chemical compound(s) as it passes through the aggregate (S), reaches the inside of said perforated mini-drains (23) in which said fixing filaments (24) collect the chemical compound(s). |
