The invention relates to a disposable self-drying filtering membrane storage box, belongs to the field of filtering membrane storage and treatment devices for environment protection and occupational sanitary test, and particularly relates to a novel filtering membrane drying storage device, which aims at completing the drying process without removal of a filtering membrane in the filtering membrane drying process. The disposable self-drying filtering membrane storage box comprises a storage box upper cover, drying agent bags, drying agent separating plates, drying holes, a separating plate rotary shaft, a storage box lower cover and a storage box clamping buckle, wherein the storage box upper cover and the storage box lower cover are buckled and connected through the storage box clamping buckle, the two drying agent separating plates are movably connected by the separating plate rotary shaft, the drying agent bags are respectively arranged between the storage box upper cover and the corresponding drying agent separating plate, and between the storage box lower cover and the corresponding drying agent separating plate, and the drying holes are formed in the drying agent separating plates. The disposable self-drying filtering membrane storage box has the advantages that the self-drying and anti-pollution functions are realized, the testing error is effectively avoided, the carrying and operation are convenient, and the disordering of filtering membrane marks is prevented.
