摘要: | 厭氧消化是一個完善的過程,用於處理多種類型的有機廢棄物,包含固體和液體的形式。生質沼氣是有機廢物厭氧消化後的產品,可自然發生在垃圾掩埋場或在受控條件下之厭氧消化槽。生質沼氣被看作是一個重要的能源來源,可減少使用化石燃料和對進口資源的依賴。很多生質沼氣的評估研究已經在不管是區域的,全國的及全球尺度下被完成,無論如何,因為長距離轉運生質沼氣在經濟上是不可行的,故考慮到以當地的有機廢棄物資源來探討其生產生質沼氣的潛力是更合適的。
桃園縣生質沼氣潛力評估,是建立在快速評估污水處理廠、固體廢物的產生和管理及農業廢棄物等的基礎上,最後發現從生質沼氣中可得到甲烷(CH4)22.9 x 106。本研究提供了快速方法來估算出區域的生質沼氣潛力並了解到可發展什麼形式的再生能源。 Anaerobic digestion is a well established process for treating many types of organic wastes, both solid and liquid. Biogas is the product of anaerobic digestion of waste, whether occurring spontaneously in landfills or under controlled conditions in digesters. Biogas is viewed as an important energy source in current efforts to reduce the use of fossil fuels and dependency on imported resources. Several studies on the assessment of biogas potential have been made at regional, national, and global scales. However, because it is not economically feasible to transport biogas feedstock over long distances, it is more appropriate to consider local waste sources for their potential to produce biogas. An assessment of the biogas potential in Taoyuan County, based on the review of wastewater treatment plants, solid waste generation and management, and agricultural waste, found that 22.90 x 106 of methane (CH4) from biogas might be harvestable, although substantial barriers for complete exploitation exist. This study provides a rapidly method to estimate the approximate biogas potentials and give a thought where can develop the renewable energy. |
