Zusammenfassung:The invention relates to the technical field of biological fermentation treatment equipment, and particularly discloses a field biogas slurry fertilizing device. The device comprises a fermentation tank, solid-liquid separation equipment, a pressure pump and a water replenishing device which are connected in sequence; a sewage pump which works on a regular basis is arranged inside the fermentationtank; the sewage pump conveys a solid-liquid mixture in the fermentation tank to the solid-liquid separation equipment; the solid-liquid separation equipment separates a solid substance from a liquidsubstance through the filtering of a screen plate; the separated liquid substance is conveyed to a field by utilizing the pressure pump through a pipeline; and the pipeline is provided with a water supplementing pipe. According to the field biogas slurry fertilizing device, feces, sewage and other dirt are subjected to fermentation treatment through the fermentation tank, biogas generated in theprocess is conveyed to all
