行道树落叶厌氧发酵产气特性研究
Biogas Yield of Street Fallen Leaves during Anaerobic Fermentation
行道树落叶清扫后的优化处理是实现废弃物资源化利用的基础。本项目旨在探求几种常见行道树落叶厌氧发酵的特性,以期为解决城市行道树落叶清扫后的能源化利用提供技术储备。本试验选取城镇绿化中四种常见行道树(三角枫、加拿大杨、紫叶李、法国梧桐)落叶作为发酵原料,在20℃和30℃两个温度条件下,研究四种单一原料发酵产气特性。结果表明:四种常见行道树在常温条件下大部分能够正常发酵产生沼气,且持续时间较长。其中三角枫产气量最大,20℃下产气总量好于30℃;加拿大杨只能在30℃下产气,且产气量很少;紫叶李和法国梧桐在20℃和30℃的产气总量差别明显,30℃温度下产气量明显好于20℃。(1)20℃条件下,三角枫、紫叶李、法国梧桐三种落叶均能正常产气,其峰值分别为550mL/d、105mL/d和405mL/d,累积产气量分别为9062mL、540mL和4155mL;而加拿大杨不能正常产气。(2)30℃条件下,4种落叶均能正常产气,产气峰值分别为345mL/d、155mL/d、370mL/d和400mL/d,累计产气量分别为7117mL、995mL、8036mL和7907mL。
he treatment mode of street fallen leaves is the basis of waste recycles. In order to supply technical reserves to energy utilization of four common urban street fallen leaves, such as Buerger Maple(Acer buergerianum Miq.), eugene poplar(Populus canadensis Moench.), Redleaf Cherry Plum(Prunus ceraifera cv. Pissardii), London Planetree(Platanus orientalis L), the characteristics of anaerobic fermentation with the four kinds of street pure fallen leaves under two temperature (20℃ and 30 ℃) were studied. The results showed that the common street fallen leaves could be anaerobic fermentation and produce biogas under 20℃ to 30℃ and has a long enough fermentation period. Buerger Maple\
