An Integrated Biogas Generation System for Swine Farms
-
摘要: 根据可持续发展的理念，以实现资源化利用最大化为原则，针对规模化养猪场，通过设备创新和技术集成，提出了“固液分离池-联动沼气池-玻璃钢沼气储气柜”沼气发酵工艺流程，结合沼气发酵智能化控制技术，形成联动高效沼气池发酵工艺技术。通过在福建省新星种猪育种有限公司应用结果表明，该工艺技术能够显著提高沼气产量和沼气利用效率，是一种实用型生态处理技术，对发展农业循环经济有重要意义。Abstract: For sustainable agriculture to maximize resource utilization, a biogas generation technology by integrating the solids-liquid separation, methane gas generation, and fiberglass-reinforced plastic biogas storage into a system for waste treatment at swine farms was designed and evaluated. The combined system with automatic controls could be scaled up for large biogas production applications. The experimental model was implemented for observation and testing at Xinxing Pigs Breeding Co., Ltd. in Fujian. The results showed significantly improved yield and utilization efficiency of biogas as compared to the conventional devices. The technology was expected to become a model for practical ecological sewage treatment for effective agricultural recycling at swine farms.
