摘　　要：通过平行对比试验,考察了分别外加Fe2+和Fe3+的SBBR反应器对实际腈纶废水的处理效果。结果表明:外加Fe2+/Fe3+对腈纶废水处理效果较好,COD去除率在60%左右,氨氮去除率高达90%以上,氨氮出水可达国家一级B标准。在水质波动阶段,外加Fe2+比Fe3+对腈纶废水中COD的处理效果更好。Fe2+对亚硝化反应具有促进作用,外加Fe2+的SBBR反应器对氨氮的降解速率较Fe3+更快。The effect of SBR reactor with Fe^2＋ and Fe^3＋ on the treatment of acrylic fiber wastewater was investigated by parallel experiment. The results show： The addition of Fe^2＋/Fe^3＋ has a good effect on the treatment of acrylic fiber wastewater. The removal rate of COD is about 60 %, the removal rate of ammonia nitrogen is over 90 %, and the effluent of ammonia nitrogen can reach the national first grade B standard. In the stage of water quality fluctuation, addition of Fe^2＋ is better than Fe^3＋ in the treatment of COD in acrylic fiber wastewater. Fe^2＋ promoted the nitrosation reaction, and the rate of degradation of ammonia nitrogen was faster than that of Fe^3 ＋ with the addition of Fe^2＋.
