摘　　要：某化工厂以化学合成法生产分散染料,产生的染料废水具有高COD、高氨氮、可生化性差等特点,原处理工艺无法达标排放。改造工程采用铁碳芬顿+ABR+UASB+A/O+芬顿组合工艺处理该分散染料废水。运行结果表明,COD去除率达到93%,NH_3-N去除率达到82%,出水水质满足当地化工产业园区污水处理厂纳管标准。A chemical plant produces disperse dye through chemical synthesis method. Since the produced wastewater has the features of high COD, high ammonia nitrogen, poor biochemical degradation and so on, the original treated wastewater quality could not meet the discharge standard. Based on the original process, a combined process of ferric-carbon Fenton, ABR, UASB, A/O, and Fenton are adopt- ed to treat the disperse dye wastewater. Actual operation results indicated that the COD removal rate reached 93%, NH3 - N removal rate reached 82%, and all the effluent indexes could meet the specified standards for discharging in the pipe of local chemical industry park.
