摘　　要：采用电-Fenton法处理醋酸纤维素废水厌氧出水,考察了Fe/C颗粒填料、反应时间、反应初始pH值、电流密度等因素对去除效果的影响。试验结果表明:基于电-Fenton法处理醋酸纤维素废水厌氧出水,在添加Fe/C颗粒条件下,有机磷去除率可达87.5%,CODCr去除率达74.3%,出水有机磷、CODCr的质量浓度分别小于8、300 mg/L,满足CJ 343—2010《污水排入城市下水道水质标准》;最佳反应条件为:反应时间为40 min,pH值为3.5,电流密度为4 m A/cm2,在电-Fenton体系中引入Fe/C填料,可将去除效果提高10%~15%。Using electro-Fenton method to treat anaerobic effluent of cellulose acetate wastewater, the effect of Fe/C granule filler, reaction time, initial pH value, current density and some other factors on pollutants removal were investigated. The results of the test showed that, using electro-Fenton method to treat the anaerobic effluent of the said kind of wastewater, with Fe/C granule added, the removal rates of organic phosphorous and CODCrreached 87.5% and 74.3% respectively, the mass concentrations of TP and CODCrwere lower than 8 and300 mg/L respectively, which met the requirement of CJ 343—2010 Wastewater Quality Standards for Sewage Discharge to Municipal Sewers. The optimal reaction condition was： the reaction time was 40 min, the pH value was 3.5, and the current density was 4 m A/cm2. Adding Fe/C filler into electro-Fenton system could improve the removal effect by 10% - 15%.
