摘要
本文报道了利用生活垃圾厌氧发酵制取沼气及发酵残留物的综合利用。结果表明,以烂菜叶、食堂垃圾为主要原料,发酵周期50天时,池容产气率为0.456m^3/m^3·d,产气量为331升/添加kgvs,平均甲烷含量为58.5％,原料毁解率为37.5％。用厌氧消化后的残留物饲养蚯蚓比常规堆沤生活垃圾饲养蚯蚓,其增重率高28.7％,繁殖率高98.35％。用蚯蚓替代部分饲料喂鸡、貂获得成功,并且每只鸡重量比对照增加18％,产蛋率提高20.6％。貂重量比对照增加6.7％,且毛色光滑油亮。
Studies on the biogas production from urban domestic waste by anaerobic digestion and utilization of fermentation residue are represented in this paper. The experimential results should that using decayed vegetables and kitchen waste as raw material, gasproduction rate was 0.456m^3/m^3·day, biogas yield was 3311/added kg vs. The raw meterial was degraded by 37.5％. The earthworms was fed with fermented residue, their weight increased about 28.7％ and the breed rate rised to 98.35％ comparing with using the residue of composted domestic waste as the feed. Earthworms have been succesfully used to replace part of corn in feeding chiken and marten. The weight and eggproduction rate per chiken increased 18％ and 20.6％, respectively, while the weight of marten increased 6.7％.
