NOVELTY - Resource comprehensive treatment of tobacco waste includes pretreating tobacco waste; breaking; composting; blending various types of tobacco waste and process water; adding inoculums; using high-temperature dry anaerobic fermentation method to ferment the pretreated material; using biogas residues produced to prepare efficient composite microbial fertilizer; refluxing the product i.e. biogas slurry to adjust the state of anaerobic fermentation system or conducting an aerobic composting process; and using produced methane to provide electric energy and heat energy for a process system.    USE - Resource comprehensive treatment of tobacco waste to prepare efficient composite microbial fertilizer and to produce methane for providing electric energy and heat energy for a process system via cogeneration device (all claimed).    ADVANTAGE - The process realizes large treatment load, short fermentation period, great gas production amount, stable quality, simple product pretreatment and post-treatment, reduced consumption of water and energy source, and reduced operation cost; and is safe.    DETAILED DESCRIPTION - Resource comprehensive treatment of tobacco waste comprises:    (A) preparing material and putting tobacco waste in a material storing pond;    (B) pretreating the tobacco waste; breaking until the granularity is less than or equal to 30 mm; and conveying the broken material to a composting area to compost;    (C) blending various types of tobacco waste and process water; and enabling the mass ratio of carbon to nitrogen of the material be 20-30:1, where total solid (TS) content concentration is 30-35%;    (D) adding inoculums; using high-temperature dry anaerobic fermentation method to ferment the pretreated material; and    (E) using biogas residues produced in step (D) to prepare efficient composite microbial fertilizer; refluxing the product i.e. biogas slurry to adjust the state of anaerobic fermentation system or conducting an aerobic composting process; and using produced methane to provide electric energy and heat energy for a process system via cogeneration device.
