NOVELTY - The device comprises complex unit, a power supply system and a control unit. The control unit is connected to a telemetry system, a video surveillance unit, a substrate block, a preliminarily substrate preparation unit, a finishing substrate preparation unit, a substrate sterilization unit and an anaerobic methanogenic fermentation substrate unit, a residual biogas removing unit and a liquid organic fertilizer distribution unit. The biogas residual removing unit removes residue from a substrate after fermentation.    USE - The device is useful for recycling organic wastes (claimed).    DETAILED DESCRIPTION - The device comprises complex unit, a power supply system and a control unit. The control unit is connected to a telemetry system, a video surveillance unit, a substrate block, a preliminarily substrate preparation unit, a finishing substrate preparation unit, a substrate sterilization unit and an anaerobic methanogenic fermentation substrate unit, a residual biogas removing unit and a liquid organic fertilizer distribution unit. The biogas residual removing unit removes residue from a substrate after fermentation. Input ends of the liquid organic fertilizer distribution unit are connected to corresponding output ends of the anaerobic methanogenic fermentation substrate unit and the residual biogas removal unit through a main pipeline and an additional pipeline. An output end of a biogas distribution unit is connected with an input end of the anaerobic methanogenic fermentation substrate unit and the finishing substrate preparation output unit through the additional pipeline corresponding to the input end of the anaerobic methanogenic fermentation substrate. Input ends of an inoculator are connected with the final substrate preparation output unit through the additional pipeline. The additional pipeline comprises a control valve to connect a site host and a host substrate sterilization unit. The anaerobic methanogenic fermentation substrate unit is connected with an output end of the inoculator through additional pipeline. The input end of the anaerobic methanogenic fermentation substrate is connected to the host substrate sterilization unit through the additional pipeline. An additional pipework is connected with the final substrate preparation output unit and anaerobic methanogenic fermentation substrate input unit. The additional line couples an output inoculator pipeline and one-way valves. The liquid organic fertilizer distribution unit and the residual biogas distribution unit are configured to perform communication with a consumer through the main pipeline and the additional pipeline. A power control system is connected to the telemetry system and the video surveillance unit by a power conduit unit or wireless connection unit. The control and uni-directional valves are operated in a remote manner.
