Application of anaerobic digestion technology in building a circular economy model for ecological Baijiu enterprises
Baijiu brewing wastewater,distillers'grains and Baijiu brewing sludge are the main wastes in the Baijiu production process,with the dual characteristics of"pollution"and"resources".Under the background of"double carbon",the resource and high-value utilization of Baijiu brewing waste have become an urgent problem for Baijiu production enterprises.The physicochemical properties of Baijiu production waste and the applica-tion of anaerobic digestion technology in the recycling process of Baijiu brewing waste were described in detail.Based on the plant nutrition charac-teristics of biogas slurry and biogas residue,it was proposed to gradually build an ecological Baijiu enterprise circular economy model with Baijiu en-terprises characteristics,and form an ecological cycle industry chain of"agriculture+Baijiu making+tourism+agriculture",in order to provide theoreti-cal references for the green and sustainable development of Baijiu enterprises.
