摘要
为研究中高温下条件下羊粪与芒果废弃枝叶混合厌氧发酵的产沼气特性影响,选取风干后的羊粪与芒果废弃枝叶进行厌氧发酵产沼气试验.试验设置5个配比:单一羊粪、单一芒果废弃枝叶、羊粪与芒果废弃枝叶(1∶1、1∶3、3∶1)3个配比,在3种恒温温度(35 ℃、45 ℃、55 ℃)下进行厌氧发酵,共计15个处理,发酵周期32天.试验结果表明:相对于芒果废弃枝叶单一发酵,羊粪与芒果废弃枝叶混合发酵可获得较好的产气效果,但相对于羊粪单一发酵,各温度下混合发酵的产气量并没有更好的表现.综合比较,羊粪和芒果废弃枝叶混合发酵在配比3∶1、45 ℃发酵状态下的发酵完成时间最短为17天,且TS产气率和VS产气率最大,具有一定的产气潜力.
Abstract
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.
