Abstract

This study evaluates the suitability of digestate from small mesophilic biogas plants in central Vietnam for agricultural application. Digestate samples were collected from 85 farms and analyzed for microbial contamination and elemental composition. The presence of pathogens was examined after anaerobic digestion under mesophilic conditions and the impact of antibiotic resistance in microbes was investigated. Potential integration of solar energy into anaerobic digestion and biogas upgrading to biomethane was also explored. Based on experimental data and prior research, a visualization model was developed to illustrate organic waste decontamination through mesophilic digestion. A block diagram was constructed, integrating various perspectives on digestate utilization to assess the broader environmental impact of biogas technology.

越南中部在中温环境下生产的小型沼气厂的消化物：对当地农民来说是敌是友？

本研究评估了越南中部小型嗜酸性沼气厂的消化液在农业应用中的适用性。从85个农场收集了消化样品，并分析了微生物污染和元素组成。在中温条件下厌氧消化后检查病原体的存在，并研究微生物对抗生素耐药性的影响。还探讨了太阳能在厌氧消化和沼气转化为生物甲烷中的潜在整合。在实验数据和已有研究的基础上，建立了一个可视化模型来描述有机废物通过中温消化去污。构建了一个框图，整合了消化利用的各种观点，以评估沼气技术对环境的广泛影响。
