| Abstract: | The improved upflow anaerobic sludge blanket(UASB) was used for the treatment of high concentration alcohol wastewater at moderate temperature.Influencing factors during reactor initiating,formation of granular sludge and operating characteristics of the reactor were studied.When volume loading is 10.39 kg COD/(m3·d),COD removal efficiency reaches 90.2%,VFA concentration is below 300 mg/L,and average yield of methane is 0.328 m3/kg COD,optimum operational efficiency can be achieved.These provide scientific evidences for the treatment of high concentration alcohol wastewater by improved upflow anaerobic sludge blanket. |
| Keywords: | UASB alcoholic wastewater reactor start-up granular sludge |
