摘　　要：针对A2/O工艺在脱氮除磷方面存在的矛盾,以及生物难降解印染废水中碳源不足的问题,提出厌氧水解-分点进水倒置A2/O处理印染废水的新工艺。试验结果表明:新工艺仅利用2段生化处理过程,出水COD、BOD5、氨氮、TN、TP、色度分别可达77.12%、70.93%、96.59%4、5.52%、63.33%8、3.11%的平均去除率,分别比常规A2/O工艺提高16.01、27.85、3.92、8.851、9.89、0.65个百分点,显示厌氧水解-分点进水倒置A2/O工艺具有较好的污染物去除效果。In view of the conflict between the nitrogen and phosphorus removal in A2O technique, as well as the problem of insufficient carbon source in the nonbiode gradable dyeing wastewater, the anaerobic hydrolysis-step feed in the inverted A2O technique was studied in textile wastewater treatment. The results showed that the removing rates of COD, NH4＋-N, TN, TP, BOD5, chroma increased from 61.11%, 92.67%, 36.67%, 43.44%, 43.08%, 82.46%, by the routine A2O technique to 77.12%, 96.59%, 45.52%, 63.33%, 70.93%, 83.11% by the new technique. It exhibited satisfactory removing efficiencies of pollutants.
