| 英文摘要 | The effects of zero-valent iron (Fe-0) on the performance of a mesophilic upflow anaerobic sludge blanket (UASB) reactor treating high-strength wastewater from the vitamin C biosynthesis industry (VCW) was investigated during a 200-day period. The results showed that the chemical oxygen demand (COD) removal efficiency, CH4 content in biogas, specific methanogenic activity of sludge, and phosphate removal efficiency were significantly improved up to 81.8-96.1%, 76.5-79.6%, 1.71-2.87 g CH4-COD g(-1) VSS d(-1) and 68.5-85.2%, respectively, at elevated organic loading rates (OLRs) in the Fe-0-amended reactor (R-Fe). In contrast, the corresponding values of 65.3-83.4%, 69.1-70.8%, 1.12-1.95 g CH4-COD g(-1) VSS d(-1) and 1.4-1.6%, respectively, were recorded in the control (R-0). Elevated ferrous concentration of nearly 400 mg L-1 in sludge was detected in R-Fe, whereas in the effluent of both reactors it was low (<1.0 mg L-1). Batch tests further showed that Fe-0 significantly enhanced the biodegradability of the VCW as shown by an increase in BOD/COD ratio from 0.41 to 0.65, and could serve as the electron donor for methanogenesis by anaerobic sludge, which were responsible for the differences between R-Fe and R-0. The results suggest this integrated Fe-0-microbial system is promising in facilitating the anaerobic digestion of VCW in UASB reactors. |
