Abstract

The Fe/C micro-electrolysis process is adopted in treating alcohol wastewater of high concentration. The effects of Fe/C ratio and iron-to-water quantity ratio and reaction time on the removal efficiency of CODcr are studied. The results show that when the ratio of Fe/C is 3∶1 and iron-to-water quantity is 125∶500,and reaction time is 2 hours,and when influent CODcr is 42 432 mg/L,pH value is 3.83,the greatest removal efficiency of CODcr reaches 35%,and the BOD5/CODcr of alcohol wastewater is improved from 0.35 to 0.52. As a pretreatment process,it reduce the load on the later process,and decrease the let of greenhouse gas-methane.
