摘　　要：基于氢基质生物膜反应器MBf R,研究了进水p-NCB浓度、氢气压力和硝酸盐对p-NCB生物还原降解效果的影响。增加进水p-NCB浓度并未明显影响其去除率,氢气压力对p-NCB的还原有正面效应,由于电子供体竞争及毒性中间产物,水中共存的硝酸盐对p-NCB的生物还原具有抑制作用。通过短期实验发现,MBf R的生物降解效果较好,去除率最高达94.2%。利用MBf R处理含p-NCB污染物的污水,有一定的应用潜力。Based on hydrogen-based membrane biofilm reactor MBfR,the effects of influent p-NCB concentration,hydrogen pressure and nitrate on p-NCB bioreduction degradation were studied.The increase of influent p-NCB concentration did not significantly affect its removal rate,hydrogen pressure had a positive effect on p-NCB reduction,and the coexisting nitrate in water inhibited p-NCB bioreduction due to electron donor competition and toxic intermediates.Through short-term experiments,it was found that the biodegradation effect of MBfR was good,and the removal rate was as high as 94.2%.MBfR had a certain application potential in the treatment of wastewater containing p-NCB pollutants.
