摘要采用NaOH改性活性炭纤维(ACF)活化过硫酸盐(PMS)深度处理焦化废水及降解吡啶.考察了NaOH-ACF投加量、PMS浓度、初始pH值对焦化废水生化出水中化学需氧量(COD)、色度去除效果及吡啶降解效果的影响.结果表明,NaOH-ACF/PMS体系可以有效去除焦化废水中的有机物和色度,并完全降解吡啶.材料表征结果表明,NaOH-ACF具有丰富的表面官能团,吸附和催化性能良好.NaOH-ACF投加量为2.0g/L、PMS浓度为6.0mmol/L、初始pH值为7.0、温度为25℃,反应120min,焦化废水生化出水中COD和色度的去除率分别达85.7%和93.8%,吡啶初始浓度为10mg/L,降解率为100%.发光细菌毒性实验表明,在最佳反应条件下NaOH-ACF/PM体系深度处理焦化废水可以有效脱毒.自由基鉴定实验证实,NaOH-ACF/PMS体系中同时存在硫酸根自由基(SO₄^-·)和羟基自由基(·OH).气相色谱-质谱联用(GC-MS)分析显示,焦化废水生化出水中的大分子、复杂有机物在体系中完全矿化或者转化为小分子物质,吡啶通过羟基化和去氢作用可以完全降解.

Abstract：In this study, NaOH-modified activated carbon fiber (ACF) was used to activate peroxymonosulfate (PMS) for the advanced treatment of coking wastewater and degradation of pyridine. The effects of NaOH-ACF dosages, PMS concentrations, and initial pH values on chemical oxygen demand (COD), chroma, and pyridine removal efficiency were investigated using batch experiments. Experimental results indicated that NaOH-ACF/PMS system could effectively degrade organics and chroma, and completely degrade pyridine. The characterization analysis showed that NaOH-ACF had many surfaces functional groups and preferable performance of adsorptive and catalytic. The removal efficiency of COD and chroma reached to 85.7% and 93.8% after the treatment of 120min, respectively, under the optimal conditions of 2.0g/L NaOH-ACF, 6.0mmol/L PMS, pH 7.0, and reaction temperature 25℃. Under the same conditions, the degradation efficiency of pyridine reached to 100% with the initial concentration of 10mg/L. Photobacteria acute toxicity tests showed that the detoxification could be achieved under the optimal operation by NaOH-ACF/PMS system. Free radical quenching experiments confirmed the existence of both SO₄^-· and ·OH in the system. GC-MS analysis presented that those complex substances of macromolecules in coking wastewater could be effectively removed and further converted into small-molecule matters in the NaOH-ACF/PMS system. In addition, pyridine could be completely degraded through hydroxylation and dehydrogenation.
