Furthermore, a desulfurization device that performs desulfurization and biodegradation of methane through biological deodorization can also be adopted. When the amount of gas introduced into the desulfurization equipment is large or the sulfur concentration is high, the reducing sulfide can be recovered as a sulfide such as sodium sulfide by wet desulfurization, or absorbed in a ferric sulfate solution. A device configured to generate and recover vehicle body sulfur can be suitably employed.
