摘要

本研究探討雙酚A與有機廢棄物批次式厭氧消化影響，針對不同濃度的影響以及消化產物的再利用評估：根據本研究結果顯示，批次式厭氧消化，污泥活性與BPA濃度成反比，濃度越低被抑制效果越差，BPA濃度10 ppm產氣量以幾乎與控制組相同，有研究顯示BPA與有機固體廢棄物共消化使用半批次進出有機固體廢棄物基質，持續操作以後，BPA濃度10、100 ppm可促進污泥活性1~2.46倍(吳，2013)，但本研究使用批次試驗則無促進反應產生。發芽試驗結果顯示，純污泥500 ppm發芽速率最快，根據產氣量活性趨勢判斷，因500 ppm之污泥活性遭到抑制，有機物消耗量降低，造成最終消化產物有機物含量較其他濃度高，而造成發芽率之影響。

This study explores the influence of bisphenol A and batch anaerobic digestion of organic solid waste, in view of the influence of different concentration and reuse evaluation of digestive products: according to the result of this study, it indicates that batch anaerobic digestion, activity of anaerobic sludge is in inverse proportion to concentration of BPA, the lower concentration, the poorer inhibited effect. The gas production rate of 10 ppm concentrations of BPA is almost the same as the inhibition group. There are research shows that BPA and organic solid waste takes semi-batch operation, feed and discharge with substrate of organic solid waste, after continuous operation, 10, 100 ppm concentration of BPA can accelerate activity of anaerobic sludge of 1~2.46 times(Wu, 2013). However, this study makes batch experiments and can’t find any accelerating reaction. The result of germination test indicates that when the percentage of pure anaerobic sludge is 500 ppm, the germination percentage is the fastest. Judged according to the activity trends of gas production rate, since the activity of 500 ppm anaerobic sludge is inhibited, the consumption of organic materials reduces, makes the concentration of organic material content of the final digestion product higher than others, and affect the germination percentage.
