NOVELTY - A sewage sludge treatment device comprises a feeding conveyer belt, a fermentation barrel, an earthworm cultivation bed and an earthworm reaction bed, which are orderly connected with a feeding conveyer belt. A motor (3) and a blower fan are arranged at the bottom of the fermentation barrel. A mechanical stirring rod (5) is arranged in the fermentation barrel. Excrement scrapers are arranged on the earthworm excrement separation screens, and earthworm excrement collection grooves are arranged on the lower parts of the earthworm excrement separation screens.    USE - Device for treating sewage sludge.    ADVANTAGE - The device has simple operation, and achieves the synchronous cultivation and treatment of earthworm. The excrement scraper can promote the earthworm excrement to separate and prevent anaerobism at the bottom of a pile.    DETAILED DESCRIPTION - A sewage sludge treatment device comprises a feeding conveyer belt, a fermentation barrel, an earthworm cultivation bed and an earthworm reaction bed, which are orderly connected with a feeding conveyer belt. A motor (3) and a blower fan are arranged at the bottom of the fermentation barrel. A mechanical stirring rod (5) is arranged in the fermentation barrel. A spiral blade and a vent hole are arranged on the mechanical stirring rod. The lower end of the mechanical stirring rod is connected with the blower fan and is driven by the motor. One side of the fermentation barrel close to the earthworm cultivation bed is provided with a movable discharge door. Earthworm excrement separation screens are laid on the earthworm cultivation bed and the earthworm reaction bed. Excrement scrapers are arranged on the earthworm excrement separation screens, and earthworm excrement collection grooves are arranged on the lower parts of the earthworm excrement separation screens.
