Deodorization treatment system and method for hazardous waste incineration material pit

The invention discloses a deodorization treatment system and method for a hazardous waste incineration pit, and belongs to the technical field of hazardous waste odor treatment. The deodorization treatment system comprises an odor collection system, a flow distribution system and a deodorization purification system. Odor is collected and gathered to a main pipeline through the odor collecting pipeline, and introduced to subsequent odor treatment equipment; a fireproof valve is arranged and is automatically closed under the condition of abnormal temperature rise; fire is prevented from spreading along a pipeline, the air volume of each collection point is adjusted through an air valve, the collection effect is guaranteed, then odor is subjected to flow distribution treatment through an airvolume adjusting valve on a three-way pipeline, and part of odor is led to an incineration system through an incineration system air pipe and an incineration system fan to serve as combustion-supporting air to be subjected to
