NOVELTY - Anaerobic fermentation involves recycling the waste, straw is placed in the chitosan modified liquid for 10-20hour, then sent into the constant temperature box for 1-2 days, the temperature in the constant temperature box is 60-70 degrees Celsius, then taken out, sent into the steam blasting machine for blasting, the blasting pressure is 1-3MPa, the reaction is ended, water washing is done, dried, straw is placed into the ionization liquid for ionization treatment, the ionization current is 1-5A, the ionization time is 10-20 hours, then washed and dried, sending the straw to the fermentation tank, adding fermenting agent into the fermentation tank, then adding acetic acid-sodium acetate buffer solution, anaerobic fermenting for 1-3 days at 40-50 degrees Celsius to obtain the product. USE - Method for anaerobic fermentation used for improving utilization of waste straw (claimed). ADVANTAGE - The method uses chitosan modified liquid to process the waste straw, the chitosan modified liquid preparation adopts bentonite to improve graphene, graphene is sheet structure and bentonite belongs to layered structure, after modification, applied in chitosan solution with high compatibility of chitosan, is compatible with the straw so that the bentonite improves graphene for processing straw, at last through, blasting treatment break the straw surface, at the same time, using ionization liquid further breaking straw surface the straw of the lignin.
