| 中文摘要: |
| 为了探索湿地水生植物厌氧发酵的可行性,以香蒲、香菇草、再力花、菖蒲、美人蕉、紫芋、梭鱼草为发酵原料，在中温（37℃）条件下，进行批量发酵试验。结果显示：这7种水生植物产气率分别为513.23、539.09、577.96、508.95、555.05、629.41、473.09mL/g（VS),说明水生植物是较好的发酵原料。通过对7种水生植物的产气性能进行分析，得出原料的水解酸化是影响水生植物产气率的主要因素。木质纤维素对厌氧产沼气的影响在本试验表现为：木质素与厌氧生物产沼气潜力（ABP）之间的相关性（R2=0.067，P>0.05）很微弱，而半纤维素与ABP 之间有一定的相关性（R2=0.610，P<0.05）。 |
| 英文摘要: |
| In order to explore the feasibility of using wetland aquatic plants for anaerobic fermentation, Typha orientalis Presl, Hydrocotyle vulgaris, Thalia dealbata, Acorus calamus Linn, Canna indica, Colocasia tonoimo Nakai and Pontederia cordata were explored as fermentation material by batch model at moderate temperature (37℃)in this paper. The results showed that the biogas production rate of the seven aquatic plants were 513.23, 539.09, 577.96, 508.95, 555.05, 629.41, 473.09 mL/g (VS) respectively, which suggested that the aquatic plants can be utilized to be resource for biogas production. The characteristics of the 7 kinds of wetland aquatic plants for biogas
production were studied, which indicated that the hydrolytic acidification of the aquatic plants was the main factor that affected biogas potential. The relationship between lignocellulose and anaerobic biogasification potential (ABP) in this experiment was as follows, the correlation between lignin and ABP (R2=0.067, P>0.05) was very weak, while there was a certain correlation between hemicelluloses and ABP (R2=0.610, P<0.05). |
