摘　　要：介绍了铁炭微电解法对硝化废水的处理方法及效果。实验表明,硝化废水经该方法处理0.5h,废水中硝基苯和硝基氯苯的去除率可达到90％,COD_(Cr)最大去除率可达50.6％;酸性硝基苯废水经本方法处理后BOD_5/COD_(Cr)可从0.01～0.02提高至此0.27～0.60,废水的可生化性明显提高。但酸性硝基氯苯废水经该方法处理后BOD_5/COD_(Cr)未见明显提高。The treatment method and its efficiency on treatment of nitrified wastewater by Fe/C micro-electrolysis were described in detail in this paper. The experiment indicated that when nitrified wastewater is treated for 0.5h, the removal efficiency of nitrobenzene and nitrochlorobenzene reached 90%, The greatest removal efficiency of COD_(Cr) reached 50.6%. After treatment, the BOD_5/COD_(Cr) of acid nitrobenzene wastewater improved from 0.01～0.02 to 0.27～0.60, and the quality of biochemistry improved greatly but the BOD_5/ COD_(Cr) of acid nitrochlorobenzene wastewater did not improve.
