摘要
文章以城市有机垃圾和羊粪为发酵原料,研究了在中温(35℃)条件下不同原料配比对厌氧消化过程及消化效率的影响。结果表明,城市有机垃圾和羊粪进行联合厌氧发酵可以提高原料的消化效率。当城市有机垃圾和羊粪TS比为1∶2时厌氧消化效果最好,COD去除率达52.73%,TS去除率达47.39%,VS去除率达54.93%,累计产气量最大且甲烷含量较高。
Anaerobic fermentation of municipal organic garbage mixed with sheep manure was studied under condition of different mixing ratio and temperature of 35 ℃. The results showed that the co-digestion of municipal organic garbage and sheep manure could improve the efficiency of garbage digestion,the TS mixing ratio of municipal organic garbage and sheep manure of 1∶ 2 obtained the best result,with the COD degradation rate reached 52. 73%,TS degradation rate 47. 39%,and VS degradation rate 54. 93%. The accumulative biogas production obtained the maxium of 12863 m L,and the methane content was high.
