摘　　要：采用ABR厌氧反应器强化处理印染废水,小试结果表明,随着停留时间(HRT)的缩短,COD和色度去除效果逐渐变差,COD去除率和BOD5/COD比值下降明显,色度下降缓慢。HRT为24 h,基本满足COD的降解、BOD5/COD的提高和色度的去除要求。ABR示范工程运行结果表明,COD平均去除率为34.8%,色度平均去除率为60.8%,BOD5/COD提高至0.34,废水可生化性明显改善;ABR出水中,脂类和杂环类明显减少,水质得到进一步改善。An anaerobic baffled reactor（ABR） is used to printing and dyeing wastewater treatment. The results of the experimental research indicate：with HRT shortens, the removal efficiency of COD and color become poor gradually. The removal of COD and BOD5/COD drops rapidly, while the removal of color declines slowly. With HRT 24 h, it can meet the demand of degradation of COD, improvement of BOD5/COD, and removal of color. The results of the ABR project indicate：the total removal efficiency of the COD and color of the system are 34.8% and 60.8% respectively,BOD5/COD increases to 0.34. The results of GC-MS analysis show that lipids and heterocyclic in effluents after ABR treatment are significantly reduced.
