摘　　要：以微电解为预处理,与生化处理直接结合,考察了该工艺对对硝基苯酚的处理效果。结果表明,微生物经过合理的驯化后,在短期内获得对对硝基苯酚较好的适应性与处理效果,不同质量浓度负荷下微生物都能够将对硝基苯酚的质量浓度降低到1～2mg·L-1,只是随着负荷的提高,降解的时间也不断延长。组合工况在对硝基苯酚含量较高时,系统运行稳定,能够较好提高整体去除效率,出水对硝基苯酚的质量浓度在5mg·L-1左右,COD不超过40mg·L-1,并具有一定的抗冲击负荷能力。The treatment of p-nitrophenol was studied by biotreatment combined with micro-electrolysis. The experimental results showed that through more reasonable acclimatation of microbial floc stepwisely, the better biological removal efficiencies can be obtained for wastewater containing p-nitrophenol, where the effluent concentration of subject is 1 -2 mg·L^-1 with perfect decolorization. As the load increasing, the degradation has the extension of the time. The better removal efficiencies can be obtained when p-nitrophenol is concentrated in wastewater by combined technology. The effluent concentration of p-nitrophenol is about 5 mg·L^-1 and COD is less than 40 mg·L^-1 with perfect capacity of resisting impact load.
