摘　　要：文章运用生物接触氧化法处理腈纶废水,对五种不同生物载体进行了筛选研究,确定了工艺最佳操作条件。结果表明接触氧化工艺处理腈纶废水的适宜进水负荷范围是2.06~3.55kg COD·m^(-3)·d^(-1),在本研究的所有运行条件下,1#载体(纳米凹凸棒土复合亲水性聚氨酯泡沫微生物固定化载体)均表现出最佳的污染物去除效果。接触氧化工艺对特征污染物N,N-二甲基乙酰胺(DMAC)和丙烯腈的去除率接近100%。Biological contact oxidation process was used in the treatment of acrylic fiber wastewater.Five different biomass carriers were compared and the operation conditions were optimized.It is indicated that the optimal influent organic loading rate of acrylic wastewater by biological contact oxidation process was 2.06~3.55kg COD·m-3·d-1.Under all operating conditions of the study,1#carrier(nano attapulgite composite hydrophilic polyurethane foam immobilized carrier)showed the best pollutant removal effect.The removal rates of N,N-Dimethylacetamide(DMAC)and acrylonitrile,which are two typical contaminants in acrylic fiber wastewater,were both almost 100%.
