摘　　要：硝基苯和苯胺生产中产生的废水含有的大量硝基苯、苯胺类物质及其衍生物。这些物质的生物可降解性较差,并对生物具有毒性。对含硝基苯和苯胺的废水采用ClO2催化氧化技术进行处理后,硝基苯和苯胺的去除率均可达到95%以上,COD的去除率可以达到90%;出水中硝基苯、苯胺和COD的浓度分别降到2.5mg/L、1.5mg/L和100mg/L以下。A considerable amount of nitrobenzene, aniline and its derivative that are toxic to organism and difficult to degrade are generated in wastewater from nitrobenzene manufacturing process. After nitrobenzene and aniline wastewater was treated with ClO2 catalytic oxidation process, removal efficiency of COD, nitrobenzene and aniline were up to 90%, 95% and 95% respectively, with concentration of nitrobenzene, aniline and COD under 2.5mg/L, 1.5 mg/L and 100 mg/L respectively.
