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.

猪粪，水葫芦和家禽粪便共同消化产生沼气的评估

在这项研究中，研究了猪粪，水葫芦和家禽粪便共同消化产生的沼气。将500毫升的生物消化器串联连接，并使用水置换法估算产生的沼气量。猪粪与水葫芦与家禽粪便的重量分布百分比之比为（0:40:60），（30:40:30），（15:40:45），（45:40:15 ）和（60：40：0）分别位于消化器A1，B2，C3，D4和E5中。Digester C3中获得的最高沼气累积产量为307 cm ³ CH ₄ / g。气相色谱分析显示22.50 wt％（CO ₂），64.92 wt％（CH ₄）和4.83 wt％（N ₂）表示产生的沼气可用于农村和城市社区的房屋做饭和取暖。
