The study on micro-electrolytic degradation of the CODCr of secondary effluent water from refinery

摘要：

　　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.
