摘要

    摘要
  • 摘要: 为了破坏丙烯腈的氰基键(C≡N)，降低丙烯腈废水的毒性，采用铁炭微电解系统处理浓度为100.0 mg/L的丙烯腈模拟废水。为了避免活性炭吸附的影响，建立铁炭微电解和活性炭对照试验两套系统。结果表明，铁炭微电解系统能够有效地分解转化丙烯腈，破坏丙烯腈分子结构中的氰基键(C≡N)，降低其毒性。铁炭微电解处理丙烯腈废水时，主要依赖铁炭之间形成的自由氢基[H]和新生成的Fe2+的化学氧化还原作用分解转化丙烯腈，而活性炭仅具有一定的吸附能力。铁炭微电解系统能够使丙烯腈废水中氮的形式发生转变，而不具备脱氮能力。
    Abstract: In order to damage the molecular structure of C≡N and reduce the toxicity of acrylonitrile wastewater, iron-carbon micro-electrolysis was used to treat the simulation wastewater with the concentration of 100 mg/L. Iron-carbon micro-electrolysis system and activated carbon control experiment were established to avoid the effect of activated carbon adsorption. The results showed that iron-carbon micro-electrolysis system could effectively decompose acrylonitrile, damage the molecular structure of C≡N and decrease toxicity. When acrylonitrile wastewater was treated by micro-electrolysis, it mainly depended on chemical oxidation reduction effect of the free base [H] and Fe2+ that formed between iron and carbon, while the activated carbon only had a certain adsorption capacity. The iron-carbon micro-electrolysis system could change nitrogen form in acrylonitrile wastewater, rather than have the denitrification capacity.
