Method for synergetic resourceful treatment of wine brewing waste and agricultural waste

The invention relates to a synergistic resourceful treatment method for brewing wastes and agricultural wastes. The method comprises the following steps: 1, pretreatment: setting an off-plant pretreatment system; 2, anaerobic fermentation; 3, biogas purification and utilization; 4, carrying out solid-liquid separation; 5, resource utilization: using part of the biogas slurry separated in the step 4 for anaerobic fermentation system backflow, conveying part of the biogas slurry to cultivated land to serve as liquid organic fertilizer, and processing the biogas residues into solid organic fertilizer for agricultural planting and breeding industry. The method can ensure the stable operation of the anaerobic fermentation system during the seasonal shutdown period of the brewery, so that the anaerobic fermentation treatment efficiency of the vinasse is improved. Meanwhile, high-added-value products such as biogas and agricultural organic fertilizer generated in the anaerobic fermentation treatment process can effe
