摘　　要：以腈纶废水为研究对象,考察了水力停留时间、溶解氧、硝化液回流量等因素对组合填料膜A/O工艺处理腈纶废水的影响。结果表明,当停留时间为14 h、溶解氧质量浓度为3.5 mg.L-1、硝化液体积回流比为200%时,COD去除率达到60%以上,TOC去除率达到60%以上,BOD5去除率可达90%以上,特征污染物DMAC(二甲基乙酰胺)和丙烯腈的去除率接近100%。With acrylic wastewater as research object,we studied to investigate the factors of the hydraulic retention time,dissolved oxygen and nitrification liquid flow to combination of packing film A/O acrylic wastewater treatment technology.The results showed that,when the HRT for 14 h,dissolved oxygen for 3.5 mg·L-1,Nitrification liquid reflux ratio for 200%,COD removal reached 60%,TOC removal reached 60%,BOD5 removal reached 90%,Characteristics of pollutants DMAC（dimethylacetamide） and acrylonitrile removal were close to 100%.
