摘　　要：采用序批式生物膜法(SBBR)处理实际腈纶污水,研究SBBR工艺处理腈纶废水的可行性和在厌氧、好氧模式下处理腈纶废水的优化参数。结果表明,SBBR工艺对腈纶废水具有较好的处理效果,COD去除率达到50%以上;在厌氧HRT为16 h、曝气时间为5 h、DO的质量浓度为4.5 mg.L-1时,对TOC和TN的去除率分别为70%和44.9%,对特征污染物DMAC和丙烯腈的去除率为100%;腈纶废水中含有难生物降解物质,单一的靠生物处理很难达到排放标准,出水需要后续处理。The sequencing Batch Biofilm Reactor was used to treat real acrylic fiber wastewater in this study. The test results showed that SBBR have a good removal efficiency when the removal rate of COD was higher than 50%; In anaerobic HRT of 16 h, aerobic 5 h, concentration of DO 4.5 mg · L^-1, The removal efficiency ofTOC, TN was 70%, 44.9%, respectively. Also its DMAC and AN removal rate was almost 100%. But recalcitreat compound in acrylic fiber wastewater, the water quality of the final effluent only by biochemical treatment can not meet wastewater discharge standard, so the water of effluent need subsequent treatment.
