摘　　要：以半连续厌氧发酵试验为基础，探讨了在15，25，35℃，HRT=36d和25d条件下，猪粪、鸡粪和牛粪3种厌氧发酵原料的产气特性。结果表明，3种原料均适宜在温度为35℃，HRT=25d的条件下厌氧发酵。发酵池容产气率分别为0．87～1．75，0．81～1．26，0．41～0．73m3／（m3·d）；原料TS产气率分别为0．27～0．55，0．25～0．49，0．13～0．23m3／kg。The semi-continuous anaerobic digestion experiments on biogas production characteristics of pig dung, chicken manure and cattle dung were carried out, and the experiment condition is, t= 15, 25, 35℃, HRT（hydraulic retention time）=36, 25 d. The results demonstrated that the suitable condition for anaerobic digestion of the three kinds of manures is, t=35℃, HRT=25 d, The volumetric biogas yield rates are 0.87-1.75 m3/（m3-d）,0.81-1.26 m3/（m3-d）,0.41-0.73 m3/（m3-d）respectively, the feedstock based biogas yield rates are 0.27～0.55,0.25-0.49,0.13-0.23 m3/kg respectively.
