摘要: 畜牧排泄物所排放的温室气体 (GHGs) 为目前全球能源及环境的重要议题。农业及畜牧废弃物为台湾最丰富的有机废弃物,于 1995-2007年间,处理畜牧排泄物所产出的甲烷估计量为 36-56 Gg/year;根据猪只粪便的特性,甲烷产出潜能之最大值可达 400 Gg/year。国内畜牧废水主要采用农委会畜产试验所所研发的三段式废水处理系统。废水处理后会产生大量污泥,且污泥含高浓度之有机物,亦即具甲烷产出潜能;若污泥未经适当处理回收再利用,将造成环境二次污染。为降低温室气体排放以减少对自然环境之冲击,建立有效的污泥处理及资源回收再利用技术,是现今世界各国努力的方向。畜牧污泥经厌氧消化反应产出生物气体 (biogas) 为减少温室气体排放的有效方法之一。本计画目的为评估厌氧生物技术处理畜牧污泥,以降低温室气体的排放。本计画的重要工作项目为畜牧污泥产量、污泥种类、污泥性质之调查分析,推估污泥厌氧消化降解挥发性固体物及产生甲烷,评估温室气体减量之潜势。研究成果可提供政府相关单位针对畜牧废弃物增进温室气体减量管理法规及政策之参考。 
The emissions of greenhouse gases (GHGs) from livestock wastes?(including wastewaters)?are becoming significant energy and environmental issues in the world. Agricultural and livestock wastes in Taiwan have been recognized as the most abundant organic wastes. The potential of methane generation from livestock manure management in Taiwan during the period of 1995-2007 has been estimated to range from 36 to 56 Gg/year. Based on the characteristics of swine manure, the maximum potential of methane generation could reach to around 400 Gg/year.?Currently, the piggery wastes from hog farmers are mostly treated by the three-step wastewater treatment.?It generates?large amount of sludge at wastewater treatment plants. Handling and disposal of sludge need considerable attention because of its high organic content. To prevent emissions of greenhouse gases (GHGs) to the natural environment it is necessary to develop an optimal recycling biotechnology from production to utilization. Biogas production from anaerobic digestion of livestock sludge and slurries is an effective way of reducing greenhouse gas emissions. The purpose of the proposed project is to evaluate the potential of using anerobic biotechnology for?converting?livestock?sludge into biogas and reducing emissions of GHGs.?This?project is forcused ?to investigate the production and characterization of sludge generated in the three-step wastewater treatment. Based on the results of investigation, we can assess the potential of GHGs emissions reduction. The antipated results will be valuable references for governmental regulations and policies for promoting?GHGs emissions?from livestock wastes management.
