Abstract In order to solve the problems of low biogas production rate and long fermentation time in straw anaerobic fer-
,
mentation medical stone and zeolite were experimented as adsorption-type additives for anaerobic fermentation of cornstalk.
,
The degradation rate biogas production rate and material energy conversion rate of cornstalk were determined and analyzed.
The results showed that the adsorption-type additives could be the carrier of the anism during the anaerobic fermen-
,
tation which was conducive to the enrichment of bacteria. The biogas production peak appeared early with addition of med-
