摘要： 本研究以猪粪、水葫芦、鸡粪为原料，进行共同消化产生的沼气研究。将500ml沼气池串联连接，采用水置换法估算产气量。猪粪、水葫芦和家禽的重量百分比分布在消化池A1、B2、C3、D4和E5中的比例分别为：（0:40:60），（30:40:30），（15:40:45），（45:40:15）和（60:40:0）。沼气池C3产气量最高，达到307cm3 CH4/g。气相色谱分析表明，所产沼气分别为22.50wt%（CO2）、64.92wt%（CH4）和4.83wt%（N2），可用于农村和城市居民家庭的做饭和取暖。

Abstract: In this study, biogas production from co-digestion of pig dung, water hyacinth, and poultry droppings was investigated. 500 ml bio-digesters were connected in series and water displacement method was used to estimate the amount of biogas produced. The ratio of the percentage weight distribution of pig dung to water hyacinth to poultry dropping was varied as: (0:40:60), (30:40:30), (15:40:45), (45:40:15), and (60:40:0) in digesters A1, B2, C3, D4 and E5, respectively. The highest biogas cumulative yield of 307 cm3 CH4/g was obtained in Digester C3. The gas chromatography analysis showed 22.50 wt% (CO2), 64.92 wt% (CH4) and 4.83 wt% (N2) which implied that the biogas produced can be used for cooking and heating of homes in rural and urban communities.
