摘　　要：采用铁碳微电解联用Fenton氧化法分别处理模拟煤化工废水和实际废水。处理模拟废水,铁碳微电解法COD去除率达到52%,Fenton氧化法的COD的去除率为62%。铁碳微电解法处理实际煤化工废水,最佳的反应条件为pH值等于3,反应时间为3小时,铁碳质量比为1∶2,铁粉投加量为50g/L,出水COD去除率为25%。出水进行Fenton反应,COD去除率增加到30%。铁碳微电解联用Fenton氧化法对煤化工废水的处理效果比这两种方法单独处理的效果好,并且在铁碳微电解方法之后,Fenton氧化法的处理效果有所提升。Iron-carbon micro-electrolysis combined with Fenton oxidation can be used to treat simulation coal chemical wastewater and actual wastewater.In the treatment of simulation wastewater,the COD removal could reach 52%through iron-carbon micro-electrolysis method,and the COD removal could reach 62%through Fenton oxidation method.When iron-carbon micro-electrolysis is used to treat actual coal chemical wastewater,the optimum reaction conditions are as follows:pH 3,reaction time 3h,mass ratio 1:2 of iron-carbon,iron powder dosage 50g/L,and COD removal 25%.COD removal could rise to 30%after Fenton reaction.The iron-carbon micro-electrolysis combined with the Fenton oxidation method has a better effect on the treatment of coal chemical wastewater than the two methods alone.The treatment effect of the Fenton oxidation method can be improved after iron-carbon micro-electrolysis.
