摘要

大型連續式高速醱酵系統之規劃與設計能達到農產廢棄物之滅容與減量，並轉化為其經濟環保效益之有機肥。不僅能使垃圾與廢棄物減量，降低垃圾掩埋場與焚化爐之作業負擔，且能提供廉價之有機肥料，減少化學肥料之使用，有利於有機農業之推動。本研究與得盛興公司進行產學合作，已完成醱酵菌種（Formula 101）及小型試驗機之醱酵試驗，針對醱酵溫度、通風車、攪拌頻率等條件進行最佳化測試，以作為大型連續式高速醱酵系統設計與安裝測試之重要參考依據，避免重複測試及設備修改所造成之時間及經費損失。依據宜蘭地區之農產廢棄物資源調查結果顯示禽畜糞尿固形物及肉雞飼養所使用之稻殼墊料總量高達八萬餘公噸，而依各種作物栽培面積估算之有機質肥料總需求量約45萬噸。待大型連續式高速醱酵系統完成設置並正常運作後，預期達到農產廢棄物之滅容與減量，並轉化為具經濟環保效益之有機肥。為配合二次醱酵階段，考量資材含水率及碳氮比與作業能源損耗等因素，此項高速醱酵系統宜採用55°C醱酵溫度、568 liter/min通氣量及攪拌3 min／停止3 min攪拌頻率之作業條件，可獲致較佳之醱酵結果。

Development and design of large scale, high speed, continuing composting system can reduce the volume and weight of the agricultural waste more efficiently. The agricultural waste can be turned into valuable organic fertilizer. Besides, composting process can reduce the loading of the garbage landfill and incineration plant; provide low cost of the organic fertilizer; lower the usage of the chemical fertilizer, which is good for the extension of the organic agriculture. This study was a cooperative research project between Bio-Way Biotechnology Company and National Ilan Institute of Technology. Formula 101 micro-organisms and a 80 liter fermentator were used to evaluate the optimum operating conditions (temperature, air flow rate and agitating frequency). These testing results can be used for the design and development of the large scale, high speed, continuing compo ting system. Based on the survey of agricultural waste materials in I-Lan county, the total amount was estimated about 450,000 tons. According to the agricultural production area in I-Lan county, the requirement of organic fertilizer was about 80,000 tons. Once this large scale composting system was built, it can reduce the amount of the local agricultural and food processing waste materials, and transfer waste materials into organic fertilizer. Considering moisture content and CIN ratio of composting materials and energy consumption, the optimal processing condition for high speed fermenting system were fermenting temperature 55°C, ventilation rate 568 liter/min, and agitating frequency - Agitating 3 min/Stop 3 min.
