摘要: The focus of this study was on sulfate-rich wastewater treatment in a novel anaerobic / micro-aerobic bioreactor system. system composed an upward-flow sludge blanket (UASB) reactor and floated bed reactor, which packed with elastic porous carriers controlled situation dissolved oxygen below 0.5 mg l−1. developed for accumulating higher amount biomass short hydraulic retention time (HRT) biological oxidation hydrogen sulfide to elemental sulfur. During long-term steady state operation, experimental results showed that average 70±6% sulfate transformed UASB reactor. Moreover, the overwhelming majority oxidized sulfur reactor; recirculation effluent reduced effectively degree inhibition caused by wastewater. In chemical d...
