摘　　要：在中温下,对不同质量比的鸡粪与城市生物垃圾的厌氧消化处理效果进行了为期50d的实验。结果表明:(1)鸡粪与城市生物垃圾质量比为1/1、1/2和2/1时的累计产气量最终分别为420、480、460mL/g(以每克挥发性固体计),高于纯城市生物垃圾(410mL/g);(2)至产气停止为止,纯城市生物垃圾、纯鸡粪、鸡粪与城市生物垃圾质量比为1/1、1/2和2/1时的甲烷平均体积分数分别为56.6%、56.6%、58.1%、56.2%、56.1%;(3)鸡粪和城市生物垃圾联合厌氧消化缩短了厌氧消化的时间,更利于沼气的产生;(4)纯城市生物垃圾、纯鸡粪、鸡粪与城市生物垃圾质量比为1/1、1/2和2/1时的厌氧消化最终的生物降解率分别为64.6%、67.4%、65.5%、68.7%和70.6%,联合厌氧消化最终的生物降解率均高于纯城市生物垃圾。Series of anaerobic digestion treatments were performed on the chicken manure, bioorganic municipal waste （BMW） and their mixtures to investigate their biogas production potential. Base on the different combination of chicken manure and bioorganic municipal waste, the experiments were conducted to 6 groups under the mesophilic condition of 37 ℃ for 50 d. The results showed that the addition of chicken manure could increase the biogas production of pure BMW; the biogas production could be increased from 410 mL/g to 480 mL/g VS. Group C （chicken manure to BMW was 1/1） presented the most stabile biogas production, and the yield was more than 150 mL/d from 5th day to 20th day. Biogas from group C contained 58. 1% of methane, which was higher than that of other groups. From the detection of initial and digested VS contents, the biodegradability of the 5 difference feedstock materials was calculated, which ranged from 64.6 % to 70.6 %. The experimental data could be well described by dynamic model, and biogas production rate constants were obtained.
