一般注記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.
