| 摘 要： | 研究了反应时间、染料浓度、进水pH以及不同的废铸铁屑投加量的条件下，废铸铁屑内电解法处理模拟印染废水的脱色能力。并采用铁屑滤床强化厌氧一好氧膜生物反应器（A／OMBR）处理含活性染料的模拟废水。研究结果表明，铁屑对模拟印染废水的最佳脱色时间为12min，酸性条件下铁屑的脱色率优于碱性条件．随铁屑投加量的增加，系统对印染废水的脱色率提高，铁屑滤床强化A／OMBR处理可以提高组合工艺出水色度和COD的去除率。

| Abstract: | Scrap iron was effective for decolorizing reactive dye wastewater due to the redox reactions taking place near surface of scrap iron which functioned as electrode of the micro-cell systems. The effects of reaction time, dye concentration, influent pH and scrap iron dosage were investigated. The optimum reaction time was 12 rain; the decolorization was better when the influent pH was acidic and/or a higher iron dose was employed. Scrap iron addition enhanced performance of the anaerobic-aerobic membrane bioreactor process; the combined treatment achieved more than 90% in color reduction and 95% in COD removal. |
