摘　　要：采用生物膜法厌氧-好氧处理腈纶废水,试验研究了不同工况条件下,工艺对腈纶废水的处理效果。试验结果表明,当厌氧水力停留时间(HRT)控制在30 h时,COD与BOD5的去除率分别为23.22%、37.57%,BOD5/COD降低17.96%。当好氧的HRT控制在24 h、气水体积比为40:1时,COD去除率58.92%。当工艺总HRT控制在54 h时,COD去除率达60%以上,BOD5去除率达95%以上,特征污染物二甲基乙酰胺(DMAC)和丙烯腈(AN)的去除率接近100%,系统运行稳定可靠。针对此腈纶废水建议厌氧HRT控制在30 h,好氧HRT控制在24 h,气水体积比控制在40:1。In the paper, acrylic fiber wastewater was treated by biofilm method of anaerobic and aerobic. The removal effect of acrylic fiber wastewater was studied under different conditions. The results showed that when the anaerobic hydraulic retention time （HRT） remained at 30h, the removal rates of COD and BOD5 were respectively 23.22% and 37.57%, respectively. At the same time, the BODJCOD decreased by 17.96%. When the aerobic HRT and the volume ratio of water and gas were respectively controlled at 24 h and 40：1, the removal rate of COD was 58.92%. The removal rate of COD was high than 60%, BOD removal was above 95%, and the removal of those characteristic pollutant such as Dimethylacetamide （DMAC） and acrylonitrile （AN） were almost 100% when the total HRT of the process remained 54 h. This suggested that the system was stable and reliable when the anaerobic and aerobic HRT were respectively controlled at 30 h and 24 h ,the ratio of gas and water was controlled at 40： 1.
