The effects of 3 different kinds of minerals (clnoptlolte,bentonite and coal ash fly)on the process of anaerobic digestion under 35 ℃ for food wastes were studied.The changes of the pH,the VFA (volatile fatty acid)and the biogas production rate as well as the cumulative biogas yield were analyzed. The results showed that clnoptlolte,bentonite and coal ash fly are all beneficial to the improving of acid inhibition as well as increasing the peak values of daily biogas production rates and the cumulative biogas yield.After 30 days of anaerobic digestion,the peak values of daily biogas production rates and the cu-mulative biogas yield of the control group are 600 mL??d-1 ??L-1 and 3 938 mL/L,respectively.The peak values of daily biogas production rates of clnoptlolte group ,bentonite group and coal ash fly group are 623,1 418 and 1 227 mL??d-1 ??L-1 ,respectively;which are higher 3.83%,136.33% and 104.50%than that of the control group,respectively.The cumulative biogas yield of clnoptlolte group,bentonite group and coal ash fly group are 5502,8206 and 6988 mL/L,respectively;which are higher 39.72%,108. 37% and 77.45% than that of the control group,respectively.The sequence of improvement efficiency to the biogas production rate and the cumulative biogas yield is:bentonite>coal ash fly>clinoptilolite.
