Study on Treatment of Cellulose Fuel Ethanol Wastewater and Application

A combination process of cellulosic ethanol wastewater treatment was described. This process includes iron-carbon micro-electrolysis-Fenton, UASB and MBR. Through the process, well get an exploration of engineering design operation parameters and pollutant removal mechanism. Test results show that if the wastewater have 5 hours micro response,36 hours to stay on the USAB and 25 hours to stay in the membrane bioreactor ,after the flocculation decollating, the COD and ammonia nitrogen indexes of the wastewater have all reached the discharge standard of the Discharge Standard of Water Pollutants for Fermentation Alcohol and Distilled Spirits Industry (GB 276312011), and the effect of the operation is stable, cost is low.
