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。

Abstract:

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 introduced. 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，electrocatalytic oxidation，photocatalytic oxidation，supercritical water oxidation，which could separate the organic pollutants or decompose them into innocuous substances via mass transfer process or through chemical reaction. Biological 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 combined technologies illustrated such as Fenton oxidation，electron bean irradiate degradation and the combined treatment processes. Finally，the current problems faced in aniline wastewater treatment were proposed，and the development prospects of aniline wastewater treatment were prosected．
