摘　　要：染料废水具有"三高一低"的特点(高COD、高色度、高含盐量、低BOD5/COD),是废水治理的难点热点之一。在前期研究的工艺(混凝、气浮、水解酸化、好氧)基础上采用Fe/C微电解系统处理好氧池出水。结果表明:在pH为3.5,铁炭比1∶1.2,反应时间35 min的条件下,COD和色度的去除率分别稳定在80%和85%以上,出水中COD在60 mg/L以下,色度在42度以下,达到《GB 4287—1992纺织染整工业污染物排放标准》一级标准。Dye wastewater is characterized by ＂3-high and one-low＂ ：high COD, high chroma and high salinity;low BODJCOD. It is one of the difficult points and hot spots in wastewater treatment. According to the research on the pocesses, such as coagulation, air flotation, anaerobic hydrolysis-acidification and oxic, Fe/C miroelectrolysis system has been used for treating the effluent water from aerobic tank. The results show that the removing rates of COD and chroma are over 80% and 85% ,respectively under the conditions of pH 3.5,Fe/C ratio 1：1.2 and reaction time 35 min. The COD concentration is below 60 mg/L and chroma in effluent is below 42 degree ,reaching the first grade of Discharge Standard of the Pollutants in Dyeing and Finishing of Textile Industry（GB 4287--1992）.
