TECHNICAL FIELD

[0001] The utility model relates to the field of hazardous waste treatment equipment, and specifically relates to a hazardous waste yard odor treatment system. BACKGROUND

[0002] Before the harmless treatment of hazardous waste, a large amount of collected hazardous waste is stacked on the yard of the warehouse or the pit for compatibility. Since the hazardous waste is complex in composition, the solid waste and leachate in the hazardous waste will emit a large amount of foul odor. If it is allowed to spread without organization, it will seriously affect the surrounding environment and the physical and mental health of the operating personnel. Although the odor of the hazardous waste is currently treated by physical adsorption, chemical oxidation, biological degradation or combustion, some of the ways take a long time and have low efficiency, which cannot inhibit the odor in time, and it is inconvenient for personnel to quickly enter the field for temporary operation. Some are easy to cause secondary pollution after treatment. Some only collect and treat the odor of solid waste and ignore the odor of leachate, which makes the odor treatment incomplete. Therefore, people hope to have a hazardous waste yard odor treatment system that can quickly inhibit the odor and facilitate personnel to quickly enter the field for temporary operation, and can long-term and synchronously treat the odor of solid waste and leachate emitted from the hazardous waste yard, so as to improve the timeliness and effect of odor treatment and reduce the impact of foul odor on the health of operating personnel and the surrounding environment. In view of this, the case arises. CONTENT OF THE UTILITY MODEL
