摘要
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）.
