The invention discloses a recycling treatment method suitable for agricultural organic solid waste, which specifically includes the following steps: (1) collecting crop straws and crushing them to obtain crop straw powder; (2) mixing them with livestock manure evenly, and then adding the The oxygen granular activated sludge is subjected to anaerobic fermentation to obtain biogas and biogas residue; wherein, the anaerobic granular activated sludge is the digested sludge of the anaerobic sewage plant, the sludge of the biogas tank or the corrupted river mud; (3) adding to the biogas residue The mesophilic microorganism performs aerobic composting to obtain organic fertilizer; wherein, the mesophilic microorganism is at least one of Bacillus endophytes, Sporothrix thermophilus, Hydrogenobacter, Thermus thermophilus and Cellulolytic bacteria thermophilic. The invention uses crop straws and livestock and poultry manures as raw materials, performs anaerobic fermentation and aerobic composting in sequence, and generates biogas and organic fertilizer respectively, which can not only turn waste into treasure, but also reduce the harm caused by burning straw to the environment, and has good advantages. environmental and economic benefits. |
