Biogas Production through Anaerobic Fermentation of Sheep Manure and Mango Waste Branches and Leaves un-der Medium-high Temperatures
To study the effects of anaerobic fermentation of sheep manure and mango waste branches and leaves under me-dium-high temperature conditions on biogas production characteristics,air dried sheep manure and mango waste branches and leaves were selected for anaerobic fermentation biogas production experiments.Five ratios were set up in the experi-ment:single sheep manure,single mango waste branches and leaves,sheep manure and mango waste branches and leaves(1∶1,1∶3,3∶1).Anaerobic fermentation was carried out at three constant temperatures(35 ℃,45 ℃,55 ℃)for a to-tal of 15 treatments,with a fermentation cycle of 32 days.The experimental results show that compared to the single fer-mentation of mango waste branches and leaves,the mixed fermentation of sheep manure and mango waste branches and leaves can achieve better gas production effect.However,compared to the single fermentation of sheep manure,the mixed fermentation does not show better gas production at various temperatures.Overall comparison,the fermentation completion time of the mixed fermentation of sheep manure and mango waste branches and leaves at a ratio of 3∶1 and a fermentation state of 45 ℃is the shortest of 17 days,and the gas production rates of TS and VS are the highest,indicating a certain po-tential for gas production.
