摘　　要：对含氰废水进行预处理可以减小废水毒性,提高废水的可生化性。本试验采用微电解芬顿预处理高浓度含氰废水,主要考察Fe/C、H2O2的投加量、pH值及HRT对处理效果的影响。通过单因素分析确定了最佳的反应条件:微电解pH=2.5,Fe/C=4:1,HRT=70min,芬顿pH=4,H2O2的投加量4ml/L,HRT=80min。Wastewater pretreatment can reduce toxicity and improve biodegradability of the cyanide wastewater, We use micro-electrolysis and Fenton pretreat high concentration of the cyanide wastewater, and ivestigate the effects of Fe / C ,H202 dosage, pH , the HRT on the treatment. We determine the optimal reaction conditions by univariate analysis： the micro-elec- trolysis ：pH = 2.5, Fe / C = 4：1, HRT = 70min;Fenton ：pH =3.5, H202 = 4 ml / L, HRT = 80min.
