Pilot-Scale Study on Advanced Treatment of Bioeffluent of Cellulosic Ethanol Production Wastewater
Using acidification combined with electrochemical oxidation and biological aerated filter(BAF)as novel process was set-up in pilot-scale to treat the bioeffluent of cellulosic ethanol production wastewater.The results showed that the optimum pH for acidification was 3 and the optimum HRT of electrochemical oxidation was 0.5 h and the optimum dosage of H2O2 was to set the mass ratio of COD/H2O2 to 1∶1.The results also showed that acidification combined with electrochemical oxidation and biological aerated filter could be used to treat the bioeffluent of cellulosic ethanol production wastewater.The last effluent COD of the advanced process was(63.8±29.4)mg·L-1,NH4+-N was(5.8±2.5)mg·L-1,two indexes could achieve the emission standard steadily.
