【摘要】 香蕉是著名的热带和温暖亚热带水果,属芭蕉科(Musaceae)植物。香蕉加工导致剩余的香蕉皮造成污染。而国内外对香蕉皮利用方面的研究也很少。在深入了解有关沼气发酵和沼气发酵残留物开发有机肥的基础上开展了香蕉皮厌氧发酵,发酵后残留物开发成有机肥的研究。实验结果表明直接将香蕉皮按常规浓度进行厌氧发酵由于发酵池内发酵液迅速酸化而很难取得成功。但是控制香蕉皮用量在80-100g／L以内可以很好的发酵产沼气。如果用量大于100g／L则易引起酸化,导致产气不正常；驯化后的菌种用于香蕉皮的厌氧发酵较普通菌种显现出了明显的优势,且总产气量较普通菌种试验组高出53.7%；35℃的发酵温度对比25℃在香蕉皮的干发酵上显现出了明显的优势,可以将发酵周期缩短10天左右,在总产气量上差别不大；对比低浓度发酵,香蕉皮用于干发酵可以有效的提高池容产气率。干发酵结束后,残留物的TS为14.90%,有机质含量26.50%,全氮含量为1.21%,全磷含量为0.35%,pH值为8.22,将发酵残留物开发为有机肥是完全可行的。更多还原

【Abstract】 Bananas are popular warm tropical and subtropical fruits, are Musaceae plant. In the process of processing bananas produced banana peel which cause pollution. And the study of the utilization of banana peel at home and abroad is few. Basis on the in-depth understanding of the and the development of organic fertilizer using biogas fermentative residue,the author had finished the research on biogas fermentation using banana peel and the development of organic fertilizer using biogas fermentative residue of banana peel. The results showed that it’s hard to be successful of biogas fermentation using banana peel directly by conventional concentration,and it due to fermentation liquid rapid acidification. But control of banana peel in the amount of 80-100 g/L is well fermented. When the raw materials more than 100 g/ L it is easy to cause acidification and gas production is not normal; Domesticated for the banana peel of biogas fermentation as compared with ordinary inoculum showed a obviously advantage, and the accumulate yield of biogas of domesticated inoculum was 57% higher than common inoculum; 35℃could shorten HRT (hydraulic retention time) 10days compared with 25℃, and the difference on total gas production is not obvious.Dry fermentation of banana peel can be effectively increase the rate of gas production of capacity pool. The TS is about 14.90%, organic matter of 26.50 percent, total nitrogen of 1.21%, total phosphorus of 0.35%,pH of 8.22 after dry fermention, and the biogas fermentative residue will be developed to organic fertilizer is totally feasible.更多还原
