バイオエタノール製造工程から排出されるサトウキビバガス水蒸気爆砕排水の処理に関する研究 The Treatment of Steam Explosion Wastewater Generated from Bioethanol Processing using Sugar Cane Bagasse ゴ　ヴァン　アン 626 Steam explosion wastewater high-rate anaerobic treatment reversible inhibition irreversible inhibition VFAs post-treatment kinetic model reaction map modification of ADM1 北九州市立大学 博士(工学) Steam explosion wastewater from bioethanol processing contains high chemical oxygen demand, high soluble total organic carbon, low pH, strong odor and dark brown color which cause serious environmental problems. In this regard, anaerobic biological treatments are also paid attention as the potential processes. However, these process were often inhibited by the accumulation of volatile fatty acids (VFAs). In this study, irreversible inhibition under very high VFAs in decay stage was examined. In addition, to evaluate the anaerobic biological degradability of organics in steam explosion wastewater generated from bioethanol processing a batch test was conducted to elaborate a reaction map. Along with that, the high-rate anaerobic reactors (fixed-bed reactor and upward anaerobic sludge blanket reactor) were applied to treat steam exposion wastewater in continuous operation. On the other hand, physico-chemical methods (coagulation/flocculation and adsorption) after anaerobic digestion were explored to remove lignin as well as color from the wastewater. doctoral thesis 2016-09-26 VoR application/pdf 甲第97号 https://kitakyu.repo.nii.ac.jp/record/535/files/2_ゴ　ヴァン　アン.pdf https://kitakyu.repo.nii.ac.jp/records/535 eng open access
