Abstract EN
Pretreatment technology is important to the direct methanation of straw.
This study used fresh water, four bacterium agents (stem rot agent, “result” microbe decomposition agent, straw pretreatment composite bacterium agent, and complex microorganism agent), biogas slurry, and two chemical reagents (sodium hydroxide and urea) as pretreatment promoters.
Different treatments were performed, and the changes in the straw pH value, temperature, total solid (TS), volatile solid (VS), and carbon-nitrogen ratio (C/N ratio) under different pretreatment conditions were analyzed.
The results showed that chemical promoters were more efficient than biological promoters in straw maturity.
Pretreatment using sodium hydroxide induced the highest degree of straw maturity.
However, its C/N ratio had to be reduced during fermentation.
In contrast, the C/N ratio of the urea-pretreated straw was low and was easy to regulate when used as anaerobic digestion material.
The biogas slurry pretreatment was followed by pretreatments using four different bacterium agents, among which the effect of the complex microorganism agent (BA4) was more efficient than the others.
The current study is significant to the direct and efficient methanation of straw.
