Effects of Different Conditioners on Aerobic Maturation and Fermentation of Biogas Residue
As an important organic waste resource,the effective utilization of biogas residue for re-source utilization has important environmental and economic significance.The maturation process is a crucial stage affecting the degradation and transformation of organic matter in biogas slurry.This study,using biogas slurry as the primary material,designed six experimental groups incorporating u-rea,enhancers,straw,and two types of composite bacterial agents.Indoor aerobic fermentation was employed to investigate the maturation effects of different conditioners on aerobic composting.Re-sults showed that the T6 experimental group,which included enhancers,straw,and composite bac-terial agent B,achieved the best composting effect.Furthermore,Mantel tests and network analysis revealed that soil urease significantly influences microbial diversity in compost,and Chryseolinea may participate in nitrogen transformation during the composting process.These findings provide valuable reference for further research and application in biogas slurry resource utilization.
