  • The fuel ethanol production wastewater was advancedly treated by iron-carbon micro-electrolysis technology. The effects of the initial pH value,hydraulic retention time(HRT),iron to carbon quality ratio and aeration rate on the wastewater treatment performance were investigated. And the economy of advanced treatment of fuel ethanol production wastewater with the technology was evaluated. The results showed that the better treatment effects were achieved under following reactor conditions: initial pH value of 3.5,HRT of 40 min,iron-carbon quality ratio of 2∶1 and aeration rate of 1 m3/h. The treated wastewater indexes were COD of 37.8 mg/L,BOD5 of 13.9 mg/L,chroma of 10.1,turbidity of 1.2,respectively,which met the national standard of industrial water reuse(GB/T 19923-2005). The treatment cost is about 1.46 yuan/ton,by using the technology for treatment of fuel ethanol production wastewater with significant social,economic and environmental effect.
