摘　　要：采用Fe/C内电解法处理DDNP废水,研究了该方法在酸性和碱性条件下对DDNP废水的处理效果,并考察了pH值、反应时间及铁碳比对处理效果的影响。结果表明:Fe/C内电解法可有效去除DDNP废水中由硝基苯类物质引起的COD、S2-、SS和色度,在最佳酸性实验条件下,COD、S2-、SS和色度的去除率分别为85.65%、91.6%、100%和99.63%。在最佳碱性实验条件下,COD、S2-、SS和色度的去除率分别为90.13%、99.73%、100%和99.63%。The iron-carbon internal electrolysis method was used to treat the diazodinitrophenol wastewater under both the acidic and alkaline conditions and the effect on treatment efficiency by pH,reaction time and the Fe/C value was investigated.The results showed that the iron-carbon internal electrolysis method could effectively remove the COD,S^2-,SS and color index,and the removal efficiencies of COD,S^2-,SS and color index were 85.65%、91.6%、100% and 9.63%,respectively under the best acidic condition and were 90.13%,99.73%,100% and 99.63%,respectively under the best alkaline condition.
