摘　　要：利用零价铁还原性质处理硝基苯类污染物废水,可将难生物降解的有机物如硝基苯等先还原生成亚硝基苯,然后再进一步还原成可生物降解的苯胺。实验得出在室温和酸性条件下,控制反应体系的pH值和Eh值,可使硝基苯的还原率可达到97.4%。The reduction property of zero-valent iron can be used in the treatment of waste water contaminants of nitrobenzene.In this case,nitrobenzene,which is hard or impossible to be degraded biologically,can be reduced to subnitrobenzene,and further to anilin,which is easily biologically degraded.Experiment shows that in indoor temperature and acidic conditions,the reduction percent of nitrobenzene could reach 97.4%under optimal conditions.
