The Fe^0 concentration and pH had optimal values during the decolorization of X-BR in Fe^0-anaerobic biological system. When Fe0 dose, initial pH value and X-BR concentration were 400 mg/L, 7 and 100 mg/L respectively, the decolorization rate of X-BR in the integrated system could reach up to 90% after 68 h reaction. Compared with pure Fe^0 and pure microorganism treatment systems, it could be improved about 40% under the same experimental conditions. In addition, the analysis result of UV-vis spectrogram indicated that Fe^0 could promote effectively biodegrading of anthraquinone dye X-BR and its intermediate products.
