摘　　要：将甘蔗叶、小心叶薯和合欢按不同的物料配比加入到污泥和餐厨垃圾中,考察了3种园林废弃物对污泥和餐厨垃圾厌氧消化处理的影响。实验结果表明,添加小心叶薯、甘蔗叶和合欢可显著提高污泥厌氧消化的沼气总产量以及甲烷总产量。当污泥与甘蔗叶以5∶3的湿质量比混合时厌氧消化效果最佳,此时沼气总产量、甲烷总产量分别为污泥对照组的22.4、37.7倍。然而,甘蔗叶对提高餐厨垃圾厌氧消化效果的作用有限,合欢对餐厨垃圾厌氧消化具有明显抑制作用,添加合欢后沼气总产量比餐厨对照组低48%。Series of experiments were conducted to investigate the influences of 3 green wastes （sugarcane leaves,Ipomoea obscura L. ,and Acacia pennata L. ） on anaerobic digestion of sludge and kitchen wastes in lab-scale reactors. The resuits showed that the addition of green wastes enhanced sludge anaerobic digestion in biogas production and methane yields. Mixing the sludge and sugarcane leaves in the wet weight ratio of 5 ： 3, the obtained mixture exhibited the best anaerobic digestion efficiency, the total biogas and methane production were 22.4 and 37.7 times of that in single sludge anaerobic digestion group. However, sugarcane leaves showed limited effect on the improvement of kitchen waste anaerobic digestion. In contrast, the addition of Acacia pennata L. inhibited the anaerobic digestion of kitchen wastes; the total biogas production was decreased by 48 M after adding equal quantity of Acacia pennata L..
