针对印染废水可生化性差,碳源不足的问题,提出强化厌氧水解-分点进水多级A/O处理印染废水的新工艺.结果显示:新工艺出水CODCr、BOD5、NH3-N、TN、TP和色度平均去除率可达79.5％、73.6％、98.0％、61.6％、58.3和82.2％,出水水质优于常规工艺,表明新工艺对印染废水具有较好的处理效果.%In view of poor biodegradability and the problem of insufficient carbon source in the dyeing wastewater, enhanced anaerobic hydrolysis-step feed in the multi-stage A/O process was studied in the textile wastewater treatment. The results showed that the average removal rates of CODcr, BOD5, NH3-N, TN, TP and chroma reached to 79.5％, 73.6％, 98.0％, 61.6％, 58.3％ and 82.2％ respectively. The effluent quality was better than that of the routine technique, indicating satisfactory removal efficiencies of pollutants from the dyeing wastewater.
