摘要:	為了達到人工濕地植栽移除物零廢棄及資源永續利用之目標，利用人工濕地之移除植栽進行堆肥化處理，為具潛力的去化管道之一，惟堆肥化相關操作參數尚缺乏較完整之探討。整體植栽移除物堆肥化作業分為單一植栽移除物堆肥化及混合植栽移除物堆肥化二階段，其中單一植栽移除物堆肥化作業係以蘆葦為主資材(第一實驗組)，藉改變木屑、菌種及水分之添加量，以檢討最佳起始肥堆組成。另外，藉控制起始肥堆於碳氮比25左右(第二實驗組)，以檢討不同植栽移除物堆肥化過程及產品特性之差異。而混合植栽移除物係於固定木屑、菌種及水分之添加量配比條件下，改變肥堆中不同植栽移除物之混合比例(第三實驗組)，藉由堆肥化過程及產品特性之觀察及檢測，評估最適起始堆肥配比以供實務操作之參考。由第一實驗組發現，木屑及水分添加量對於以蘆葦為主資材之肥堆水分含量之影響最為顯著，且木屑的品質及添加量亦影響肥堆有機質含量；由第二實驗組發現，於控制碳氮比約25的情況下，不同植栽移除物之對肥堆pH值有較顯著的影響，其中以齒葉睡蓮為主資材之肥堆pH8.2最高；由第三實驗組發現，不同植栽移除物混合比例之堆肥化差異性不明顯；而各實驗組最終肥堆產品之有機質(約16.0~25.7%)、全磷酐(約0.02~0.05%)及重金屬含量(以砷、鎳濃度最高)未符合法規標準。經綜合評析後，本批肥堆產品不適合作為肥料使用，但各實驗組之種子發芽率仍在94~100%之間，將如何運用或處置尚得進一步深入研究。 In order to achieve the goal of zero discharge and resources recycling, composting with the botanical waste from the constructed wetland is a potential option. However, few researches were reported about this topic. In this study, the operations about composting of botanical waste were divided into two types, there’re single-botanical waste and mixed-botanical waste. In first group of composting for single-botanical waste, reed (Phragmites communis) was used as the major basis. By changing the additive amount of wood, seeding and water, the best composition of the compost pile at the beginning was evaluated. In addition, in second group of composting for single-botanical waste, the C/N ration was controlled at 25 to examine the different characteristics of compost pile between each processes and final products, using different kind of botanical waste as major basis. In third group was designed for the composting of mixed-botanical waste. By using different kind and proportion of mixed-botanical waste, the characteristics of compost pile and the final products were observed to find the best proportioning of mixed-botanical waste at the beginning for the practical operation.Based on the finding from the first group, it was found that amount of wood and water addition significantly affected the water content in the compost pile. The amount of wood addition also affected organic matter content of the products. In the second group, the results showed kinds of botanical waste had a more significant effect on the pH value of the compost pile. In the compost pile of Water Lily(Nymphaea lotus var. dentata.) the pH attained to the highest value of 8.2. It was found in the third group that the effects of the kinds and proportion of mixed-botanical waste on the characteristics of compost pile and final products weren’t significant. Additionally, the seeds germination in all groups were still between 94% to 100%. Finally, the organic matter (16.0~25.7%), phosphoric anhydride (0.02~0.05%) and heavy metals (As, Ni had maximum concentration) of the compost products were inconsistent with the governmental standards of the fertilizers.Consequently, these products weren’t suggested for the fertilizer use. However, how to use or dispose the products, it still need further discussing.
