| Abstract: |
| In order to solve the problem that coconut processing resources were wasted and environmental pollution caused by coconut wastes，this paper studied dry anaerobic fermentation technology of coconut waste. Each experimental group was put 300 g coconut wastes in and all fermentation temperature were in room temperature. The first three groups' inoculation quantities were 20%， 30% and 40%. The last group's inoculation quantity was 30%，and the coconut wastes were immersed in 6%NaOH before fermentation.The experimental results indicated that the more the inoculation quantity，the more the biogas production. The optimal range of inoculation quantity was 30% to 40%. Disposing of 6%NaOH could quicken the coconut wastes' starting speed and shorten the fermentation period， through this disposing，biogas production would increase. So research on dry anaerobic fermentation technology of coconut waste has great significance for coconut waste resources and environmental pollution. |
