摘要
针对苯胺废水,首先介绍了其产生原因、危害及处理方法,重点介绍了物理法、化学法和生物法,包括各种方法的工作原理和技术特点。物理法主要包括吸附法、萃取法、膜分离法等,一般用于预处理阶段;化学法包括湿式氧化法、化学氧化法、电催化氧化法、光催化氧化法、超临界水氧化法等,通过传质与化学反应,将水中的有机污染物分离或分解为无害物质;生物法适合处理低浓度苯胺废水,对废水的pH、物质组成、温度等都有比较严格的要求。其次,介绍了几种用于苯胺废水处理的新型方法以及联用方法,如Fenton氧化法、电子束辐照降解技术等。最后,提出了目前苯胺废水处理面临的问题,并展望了苯胺废水处理的发展前景。
The resources,the harm and the treatment technologies of aniline wastewater were reviewed firstly.The physical methods,chemical methods and biological methods for treatment aniline wastewater were mainly intro-duced.The physical methods consisted of adsorption,extraction and membrane separation,which were primarily used in pretreatment of aniline wastewater.The chemical methods included wet oxidation,chemical oxidation,elec-trocatalytic oxidation,photocatalytic oxidation,supercritical water oxidation,which could separate the organic pollut-ants or decompose them into innocuous substances via mass transfer process or through chemical reaction.Biologi-cal methods were suitable to treat aniline wastewater bearing a low concentration,and the biological methods were sensitive to pH,material composition,and temperature of wastewater.There were other new technologies and com-bined technologies illustrated such as Fenton oxidation,electron bean irradiate degradation and the combined treat-ment processes.Finally,the current problems faced in aniline wastewater treatment were proposed,and the develop-ment prospects of aniline wastewater treatment were prosected.
