| 摘 要： | 采用以Ti/SnO2+金属铁为组合阳极的铁促双电极电化学氧化法和Fenton氧化法对丙烯腈生产废水进行了处理.对比了2种方法的处理效果,考察了诸多因子对处理效果的影响及反应过程的规律.结果表明,在外加相同量H2O2条件下,铁促双电极氧化法的COD去除率比Fenton氧化法可提高约30%～35%,且可获得超过90%的色度去除率;但当H2O2初始剂量小于1700mg·L-1时Fenton试剂氧化法处理后的废水色度反而增加.外加H2O2剂量的增加强化了Fenton氧化过程,使2种方法COD去除率均随之增加.当外加H2O2初始浓度为2200mg·L-1、电压为4.0V、反应时间为180min时,双电极电化学氧化法的COD去除率达75%.2种氧化反应过程中,H2O2浓度下降速率很快,反应60min(电化学)和30min(Feuton)时几乎均被耗尽.铁阳极通电时间对铁促双电极电化学氧化法的COD去除率和电流效率影响显著.铁促双电极氧化法(外加H2O2)对丙烯腈生产废水处理效果明显优于Fenton+铁促双电极氧化法(无外加H2O2),表明前者在有机废水处理领域有较好的应用潜力.

| Abstract: | Wastewater from acrylonitrile production was treated by chemical Fenton oxidation or dual electrode iron-promoted electrochemical oxidation using Ti/SnO2 and Fe as the combined anodes.The results from the two processes were compared,and the effects of several factors and reaction behaviors were investigated.The COD removal efficiencies from the electrochemical oxidation with H2O2 added were about 30%~35% higher than those from Fenton oxidation,and more than 90% color removal was achieved by the electrochemi... |
