摘要： 为寻求非商品水果的无害化、资源化处理新途径，本研究以腐烂、病害苹果、梨为原料，通过厌氧发酵将其转化为沼气及有机肥原料。结果表明：腐烂、病害苹果的总固体(TS)、挥发性固体(VS)产气率分别可达643.24 mL/g和674.22 mL/g，腐烂、病害梨的TS、VS产气率分别可达421.14 mL/g和426.74 mL/g；经沼气发酵后，腐烂、病害苹果的原料TS、VS降解率分别为86.40%和88.20%，能源转化效率可达82.23%；腐烂、病害梨的原料TS、VS降解率分别为54.45%和59.75%，能源转化效率为50.60%。说明腐烂、病害苹果、梨均可作为良好的沼气发酵原料。

Abstract: In order to explore a new safety and recycle method for un- marketable fruits, the decayed and diseased apple and pear were used as biogas fermentation materials and the performance was investigated. The results showed that both of them could be good materials for biogas fermentation, the total solid (TS) and volatile solids (VS) biogas production rate were 643.24 mL/g and 674.22 mL/g for apple and 421.14 mL/g, 426.74 mL/g for pear, 86.40% TS and 88.20% VS were degraded in apple, 54.45% TS and 59.75% VS were degraded in pear, and the energy conversion rate for apple and pear fermentation were 82.23% and 50.60%.
