Abstract

In this paper, the degradation of CODcr of secondary effluent from refinery is completed by iron-carbon micro-electrolysis with the purpose of recycling. The optimal process parameters are determined, with the mass ratio of Fe / C being 3:2, the dosage amount of sponge iron being 15g, the reaction time being 2.5 hours, the reaction pH being 3, the range of the filler particle size being 1-2mm. Operated with optimal parameters, the removal rate of the CODcr of secondary effluent can be as high as 75% or more, improving the biodegradability of wastewater.
