This invention relates to the field of nuclear, biological, and chemical (NBC) contamination decontamination, specifically to a NBC decontamination site and method. This invention cleverly integrates public sports venues with emergency decontamination functions through a site-adaptive module. Equipped with standardized transport interfaces, it facilitates rapid deployment using conventional transportation tools, enabling the construction of sufficient decontamination areas in a short time. When folded, its compact form supports multi-layer stable stacking, significantly saving storage space. The modular water system, combined with gradient drainage and waterproof construction, utilizes the natural elevation differences of the site to form a closed-loop water system, ensuring efficient decontamination and preventing wastewater overflow. A built-in residual water treatment device facilitates rapid cleanup after operations, allowing the site to quickly return to its sports uses. This effectively overcomes the shortcomings of fixed decontamination facilities being idle during normal times and the limited capacity of mobile equipment.
