摘　　要：采用铁碳微电解工艺预处理印染废水,以COD去除率、色度去除率和BOD5/COD值为指标,研究了进水p H值、反应时间和曝气强度对印染废水预处理效能的影响。结果表明,优化的工艺参数为:进水p H值4.5,反应时间1 h,微氧曝气。在该工艺条件下,铁碳微电解工艺对废水COD、色度的去除率最高,分别能达到近50%和90%,BOD5/COD值由进水的0.24提高到0.34。Effluent treatment of dyeing wastewater using iron-carbon micro-electrolysis technology is carried out. Taking COD removal, color removal and BOD5/COD value as indicators, the influences of influent pH value, reaction time and aeration intensity on pretreatment results of dyeing wastewater are studied. The optimal process parameters are： influent pH value 4.5, reaction time 1 h, and with micro-oxygen aeration. Under the optimal process conditions, the removal rates of COD and color can reach 50% and 90% respectively, BODe/COD value increases from 0.24 to 0.34.
