| 中文摘要 | Feasibility of a 2.3 m(3) pilot-scale mesophilic upflow anaerobic sludge blanket ( UASB) reactor was evaluated for the treatment of distillery effluent from a fermentation-based vitamin C ( Vc) synthesis industry. In the 252-day test period, successful startup was achieved within 100 days using digested sludge. Afterward, the organic loading rate ( OLR) was increased gradually from 6 to 11.8 kg COD/ m(3)/ day by increasing the influent COD in steps from 5,000 to 9,000 mg/L and by decreasing the hydraulic retention time ( HRT) to 10 h. The upflow velocity was maintained at 0.52 m/h. COD removal efficiencies > 85% and biogas productivity of 3.2 - 5.9 m(3)/ m(r)(3)/ day were obtained. The biogas contained 73% of CH4. The volatile suspended solids/total suspended solids ratio of sludge increased from 0.48 at the beginning to 0.83 by the end of the reactor operation. Similarly, the specific methanogenic activity ( SMA) improved from 0.20 to 0.82 gCH(4)-COD/ gVSS . day. These results indicated that the UASB process is effective and efficient for the pretreatment of the distillery wastewater from Vc production industry. |
