Abstract

This study investigated the process performance and kinetics of mono-, and co-digestion of swine manure and corn straw focusing on swine manure content in the total substrate. Batch anaerobic digestion tests were conducted at mesophilic condition. First-order model and Logistic model were used to assess the effect of swine manure content on degradation efficiency, biogas production rate and lag phase and predict biogas production potential. The results indicated that process stability and biogas production, degradation efficiency and biogas production rate increased while lag phase time decreased with the increase of swine manure content. Additionally, swine manure content of R4 showed the best AD performance, and according to the analyzed results and kinetic analysis, it suggested that the appropriate value of swine manure content might be 70%.
