摘　　要：根据某工业园产生的高含量印染废水特点,通过分析废水处理厂原工艺存在的问题,提出了"曝气+硫酸亚铁铵/石灰水+厌氧水解"工艺进行预处理改造。改造后运行结果表明,废水处理系统对COD、BOD5、氨氮、SS、色度的去除率分别达到92.1%、94.6%、82.7%、93.2%、96.3%,出水各项指标均优于DB 44/26-2001第二时段中的一级标准。According to the high concentrations of printing and dyeing wastewater in industrial park, through the analysis of waste water treatment plant original process existing problems, puts forward the ＂aerated- ammonium ferrous sulfate/lime water-anaerobic hydrolysis＂ transformation process pretreatment. The transformation operation results shows that the removal rate of COD, BODs, NHrN, SS, and color is 92.1%, 94.6%, 82.7%, 93.2%, and 96.3% respectively; and the index of effluent are superior to the second period level standard of DB 44/26-2001.
