The Impact of 3D Printed Ruminant Biomimetic Structures on the Performance of Biomethane Production from Kitchen Waste via Anaerobic Fermentation
摘要
Abstract
[Purposes]With the development of social economy,the proportion of kitchen waste in urban solid waste is increasing.Anaerobic fermentation to produce biomethane is one of the key technologies for the energy utilization of kitchen waste.To address the long-term instability and weak resistance to external disturbances of anaerobic fermentation reactors,3D printing technology and flex-ible silicone materials were adopted to creat ruminant biomimetic components that can be applied in continuous stirred-tank reactors to improve their operational performance.[Methods]Experimental(Ruminant)and control(Control)groups were set up according to whether biomimetic components were added to the reactor.By adjusting parameters such as organic load and test temperature,the ef-fects of biomimetic components on enhancing the production and stability of biomethane in anaerobic fermentation were explored.[Findings]The results show that under a temperature disturbance of 45℃,the biomimetic components effectively stabilize the microbial community structure,thus ensur-ing the stability of the reactor operation.For Ruminant group,there is no accumulation of butyric acid,and the pH can be maintained at 6.7-7.6.The highest methane production in the Ruminant group is 217 mL·g-1·L-1·d-1,which is 39%higher than that in the Control group.关键词
