采用调节—厌氧水解—A/O（PACT）—高效澄清池—过滤组合工艺处理综合印染废水。开展了中试试验研究和示范工程研究，研究结果表明：中试系统运行稳定，对COD、色度、氨氮、总氮、总磷平均去除率分别为93.2 %，93.9 %，90.2 %,70.8 %，96.3 %；厌氧COD平均去除率分别为48.1 %；色度平均去除率分别为75.7 %；A/O（PACT）工艺对氨氮和总氮的去除效果明显，混凝沉淀工艺则对总磷去除效果最理想；中试研究和示范工程出水水质稳定，各项指标均满足《太湖地区城镇污水处理厂及重点工业行业主要水污染物排放限值》（DB32/1072-2007）。
Pilot-scale & demonstration project study of the treatment of printing and dyeing wastewater was carried out using the combined process of anaerobic (hydrolysis)-aerobic-advanced treatment. The result of Pilot-scale study indicates:the total removal efficiency of the COD, color, NH3-N, TN, TP of the system were 93.2 %, 93.9 %, 90.2 %, 70.8 %, 96.3 % respectively, anaerobic (hydrolysis) is vital to COD & color degradation, the removal efficiency of the COD & color were 48.1 %, 75.7 %, respectively, The A/O(PACT)is vital to NH3-N & TN degradation, the coagulation treatment could effectively degrade the TP. The effluent of Pilot-scale & demonstration project could satisfy 《Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant & Key Industries of Taihu Area》(DB32/1072-2007).
